  • Simon from Ketteringham with a Citroen C6 2.7 HDi 204 said:

    As do many, I took the 'if it sounds too good to be true, it probably is' approach to performance chips. But CHIP Express were recommended by an impeccable source who had had experience with their product on my model of car - a Citroën C6 with the 2.7 HDi twin turbo diesel. Following a first rate response to a query, the product has delivered in spades. Ten days and more than 1000 miles of mixed town, country, low and high speed driving later I am certainly getting more than 10% more from a gallon, and probably 15%, and the performance is markedly better. Low speed response is immediate and has eradicated what I took to be baked-in lag in a big automatic turbo diesel, and mid-range acceleration is silky smooth, including up inclines. A very good car has been turned into the excellent car I had hoped for all along.

  • Charlie from Eastleigh with a Mercedes C220 CDI BlueTEC W205 170 said:

    The "Chip" is everything you say.... my MPG coming back from Gatwick was up to 67 MPG.... due in part to the speed restrictions.... but never the less, its at least 5-8 MPG greater than before! The car also changes gear more readily as well, I have not had the opportunity to fully exercise the increase in torque yet, but I don't expect it to disappoint!

  • Matthew from Eastleigh with a Audi A5 2.0 TDI Quattro 177 said:

    This is the third vehicle I have chipped and I must say this is both the easiest and the best system I have used. Firstly the performance improvement was remarkable and gave a noticeble boost to the already lively diesel - the quattro still gripped with ease and gave a really impressive accelaration and torque. I have now done 40,000 miles with the chip (I drive a lot!) and I have flat averaged 55mpg which is superb considering I like a spirited drive. It was also very easy to fit and reassuring to know I can just remove it without trace should the car need any warranty work. Top product - happily recommend and definitely use on future cars.

  • Gary from Carrickfergus with a VW Golf MK7 2.0 TDI 150 said:

    Please feel free to 'post' this response. I recently acquired my 'tuning box' for my VW Golf (Mark 7, 150 PS) from 'CHIP Express' and have been delighted with it's acquisition. The price was very competitive when compared with other reputable suppliers. The very impressive results upon fitting were available instantaneously in that acceleration in all gears (especially the lower ones) is not only smooth but also extremely progressive. All in all I'm a very 'happy bunny' with the product, many thanks.

  • Ben from Bournemouth with a Jaguar XF MK2 20d 180 said:

    Once the chip was installed I took the car for a run. No problems with starting or tick over. No warning lights. Traffic has not allowed me to explore the performance but I'm looking forward to a run. FOLLOW UP: Running the chip has resulted in a significant increase in power, the car positively flies! This gives the much improved performance I was looking for. I would like to thank you for your excellent support and outstanding service. I can unreservedly recommend CHIP Express.

  • John from Knebworth with a Vauxhall Antara 2.2 CDTI 163 said:

    At about 4pm yesterday I ordered a chip for my brand new Vauxhall Antara, it promptly arrived at 11am this morning and took less then 5 minutes to fit, now that's what I call service! Car already feels smoother (auto box changes gears without me knowing) and the drive is now transformed, just as promised, thanks again!

  • Bryan from Northampton with a VW Eos 2.0 TDI 140 said:

    I have been delighted with the improvement to my VW EOS since fitting the Chip Express unit. The car is far more responsive and returns on average about 8 mpg more. Fitting was simple and consequently my wife having bought a new diesel Smart, the first thing to add is the relevant Chip Express. Many thanks!

  • Ron from Thetford with a Kia Sportage MK3 1.7 CRDI 116 said:

    I was a sceptic at first, then after reading the experiences others had been through I decided to give it a go. I bought a new 1.7 CRDI Sportage, not the 2ltr purely for better fuel figures. Whilst this engine pulls very well in standard form, and was returning 44-45mpg even during the first 500 miles I had to go down the CHIP Express route. Well, there is absolutely no point in forking out the extra 2 grand for the 2 litre model when you can get the 1.7 and spend much less to get 2 litre power figures. Excuse the cliché’s, but this car is transformed and by a big margin too. From what I can remember about my 2 litre test drive, my 1.7 now pulls better than the 2 litre version. The low-down grunt is remarkable and pulls like the proverbial train. Fitting took minutes and was effortless, the box was kept on factory settings, I feel there is no need to mess with it. Needless to say I am now a very happy boy and would without question take this route again. I would recommend this to any diesel Sportage owner. Many, many thanks for a remarkable product and a customer service that is rare in this country!

  • Andrew from Lochwinnoch with a Land Rover Freelander (2) SD4 190 said:

    A friend recommended one of your "gadgets" a year ago and being not-very-techno (but Scottish and keen to save money!) I bought one. The gizmo has TRANSFORMED the performance of my Land Rover Freelander 2 TD4 AND improved the fuel economy by a genuine 15%; so much so that I have bought another one for our Freelander 2 SD4 which is now a REAL Q-car! (And of course saves fuel...) I have never written a review before (though strangely I do read them and take notice of them, whilst half-believing that they are written by the owner's chums!) so to have made me pick up pen & paper so to speak - I MUST be delighted! Thanks for making technology so simple and so successful!

  • Frazer from Skirlaugh with a Vauxhall Insignia 2.0 CDTI ecoFLEX 130 said:

    A good product and a good service deserves recognition: I fitted a CHIP Express unit to my Insignia. What an amazing bit of kit! My fuel economy and performance went way up and with the mileage I do was a Godsend! On a run to Aberdeen from Hull I returned an average of 62 MPG and I drive quite energetically! I've just taken up the trade in offer and saved a few quid on a new system. The Vauxhall has now gone with 125,000 trouble free miles and I have changed car to a Volvo S60 D3. I'm looking forward to fitting the Chip Express unit and reaping the rewards, thanks guys!

  • Warren from Lockrose, Australia with a John Deere 8130 9.0 R6 215 said:

    After recent floods devastated our farm we had to re-level all the paddocks. We purchased a 3 meter wide laser bucket to pull behind our John Deere 8130. After spending many hours of working the tractor on the farm and levelling we were very disappointed in the performance of the tractor. There was no torque what so ever at below 1500 RPM and no power. We had to work it in the 1700 to 2000 RPM range this meant constantly changing gears and riding the clutch under load. Fuel consumption was up to 36 litres per hour. After fitting your chip the torque and power from 1300 RPM up was incredible and fuel consumption was max 25 litres per hour plus working in higher gears we are very happy with your product. It was easy to fit just like you said and has made it a good machine to operate.

  • Geoff from Kidderminster with a VW Scirocco 2.0 TDI 170 said:

    I have now purchased three chips and had two re-programmed. We have fitted these to two Scirocco 170 TDI's, both have a big improvement in performance and an average mpg over 26000 miles of 55 mpg. The DSG auto box could be in sixth before 40 mph. Another is currently fitted to a BMW X1 2.0d xDrive, it needed a performance boost and has a sweet spot between 2000 and 3000 rpm that just didn't exist before the box was fitted. We have seen an increase in mpg of about 5 mpg, this is a big heavy car for the 2.0 engine. One of the reprogrammed boxes is for a Porsche Panemerra 3.0 diesel! Saw big improvements on an A6 3.0 TDI which is the same engine, so looking forward to the improved mpg and smoother power delivery. I strongly recommend CHIP Express, the systems only take a couple of minutes to fit!

  • David from Cambridge with a Mercedes C219 CLS320 CDI 224 said:

    I am on third chip from Chip Express. I had one on my Rover 75 2.0 CDTi 131, then my Mazda 6 2.2D 163 and now on my Mercedes CLS320 CDI 224. I tried chips from other companies but they were all been sent back. This is the only chip I have had were you can feel the difference in the way the car performs. My Rover 75 was so much faster it was like a different car, I covered about 80.000 miles on that one. I then moved over to the Mazda 6 and would says this was a quarter as quick again and my fuel was so much better, I covered 60.000 miles with no problems. I recently upgraded my chip for use on my Mercedes CLS. The V6 engine is much smoother and more responsive. I have been using your chips for a few years now, covering thousands of miles each month as a chauffeur, your chips make driving so much better. Keep up the good work!

  • James from Callington with a Land Rover Discovery (3) 2.7 TDV6 190 said:

    May I congratulate you on this diesel tuning product as it has made a noticeable difference to my Land Rover Discovery. I have tried other diesel tuning boxes for my previous vehicles (Kia Sorento, Peugeot 206 and Vauxhall Vectra)... and they all produced slight engine stuttering under certain load conditions. The Chip Express system does not show any evidence of this and is equal to the likes of an ECU remap (which I have also had done before) for smoothness and noticeable power gains. This would be the only diesel tuning product I would recommend.

  • Neil from Isleworth with a Audi A4 MK2 1.9 TDI 130 said:

    I am writing to express how impressive your tuning chips are, I am particularly impressed with the smoothness of the power delivery. I have tried 2 previous different tuning boxes on my Audi A4 1.9 TDI 130 and sent them both back, but yours I have to say is the best one by far - thanks!!! p.s I have already recommended this to my friends and family.

  • Simon from Leamington Spa with a Citroen C5 II 2.0 HDI 163 said:

    Not very scieintific I know, but have just been to our office and back, mainly motorway, cruise control set... used where possible, journey down with the chip isolated, 68mph average, 46.2mpg at end of journey. Re-installed chip over lunch and return journey was 65mph average and 56.4mpg. Thats 10 miles more per gallon, or 20% less fuel!

  • David from Yeovil with a Jaguar X-Type 2.2D 155 said:

    I have one of your units fitted, the performance gain is terrific, more than enough for my needs! On a long journey the economy has improved from 43 to 50 mpg. I will be happy to recommend your product to others. My car is now ALL that I want and will not be replaced as previously mooted. So much power and from an oil-burner at that!

  • Chris from Elphinstone with a Land Rover Discovery (2) TD5 138 said:

    I have just fitted your chip today and what can I say? What a difference! It feels like a new car now, no more turbo lag - it now just keeps pulling, a total joy to drive. I am now looking forward to a long drive... anyone who is thinking about getting a Chip Express system should do it, you will not be disappointed!

  • Carl from Esher with a VW Golf MK6 2.0 TDI 140 GT said:

    Just fitted my chip. Very easy to fit. Very clear instructions. The improvement in performance is just what I wanted. Lots of extra torque making overtaking even easier without the tyre burning wheel spin of too much power. Perfect, saved me thousands when compared to the cost of the 170 GTD!

  • Tony from Tonbridge with a Audi A4 MK2 2.5 TDI 163 said:

    I just had to drop you a line and say that I am VERY pleased and IMPRESSED with the chip. Fitting took about 5 mins! The gear changing on the auto is now so SMOOTH you have to watch the rev counter to even notice the change, BRILL (before you would feel it going through the gears). I can also appreciate the extra PERFORMANCE (on the supplied settings). I would be more than happy to spread the word on your chips and look forward to seeing the results on fuel economy. Thank you for this truly great product.

  • Ian from Fareham with a Skoda Superb MK2 2.0 TDI 170 CR said:

    Superb Skoda - Superb economy! Just to say that I fitted the CHIP Express last weekend and I am now getting 50 MPG on and around town (compared to 44 MPG previously) and a phenomenal 59 MPG on this mornings commute to work (120 mile round trip). Previous average was 46 MPG. I was initially very sceptical about improvement but sensible use of throttle and with unit in default setting I have been blown away by the improvement! I am recommending to friends, work colleagues and family!

  • Arthur from Warfield with a Land Rover Freelander (2) 2.2 TD4 160 said:

    I am very pleased with the new unit you supplied for my Land Rover. Since I fitted it about 2 months ago when the average fuel consumption, indicated by the on-board computer, was 25.6 mpg, it is now at 33.5 and still climbing. In addition the extra power is significant and adds to the comfort and safety of the car. I would also like to express my appreciation for the prompt and first class service provided by CHIP Express.

  • Anthony from Dorchester with a Mini 2nd Gen. 2.0 D 112 said:

    I am on my 4th car using the CHIP Express and this product does what it states on the tin. However, the real issue for me has been the first class service from the team at CHIP Express. My recent car, a Mini Cooper Countryman ALL4 Auto now drives like the SD at a fraction of the cost. Well done all at CHIP Express!

  • Andrew from Thame with a BMW E90 320d 177 said:

    I have a 58 reg BMW 320D AUTO and I have recently fitted one of your Chip Express tuning systems to it. Ill be honest in that the car certainly did not need any more power than it already had. I have had four previous turbo vehicles re-mapped and was always very impressed with the results in terms of power and economy gains. Having read alot of negative comments about tuning boxes I was very sceptical about trying one. I decided to take the plunge though, for the fact that with this system I can remove it (in 5 minutes!!!) for when the car goes to the dealer as it is still under warranty. I can honestly say that this system is equally as good as a remap, but with the added bonus of being able to remove and fit in minutes. Also I now find that the Auto box shifts up gears at lower revs and holds gears under strain much easier. And WOW it really moves now!! Its easy to forget your only driving a 2.0 litre diesel. All in all I am very impressed and would recommend you to my friends and family. Fantastic product!! Well done.

  • Matthew from Norwood, Australia with a Holden Cruze 2.0 VCDI 150 said:

    I drive a 2010 Holden Cruze CDX TD and I live in South Australia. I bought your chip a few weeks ago and what a difference! The instant I plugged it in and reversed out of my driveway I felt a noticeable difference. So I decided to take it for a bit of a spirited drive around the block and it feels like a new car. The turbo lag has just about disappeared and the ability to hold a gear longer is amazing. What I find truly astounding though is that I'm probably driving a little harder (as in, when I get dirty looks from other drivers at the lights I have to smoke them) yet my fuel consumption has actually dropped by 0.2 litres per 100kms, may not sound like much but that's the average so as time goes on I’m sure it will drop a bit more. So once again guys I am really really happy with this product and will definitely be recommending it to everyone! Thanks, Matt

  • Keith from Barkestone Le Vale with a Honda 2.2i CTDI 140 said:

    Received the kit for my Honda CR-V this morning - less than 24 hours after I ordered it. Simple, clear instructions. I spent 5 minutes reading through the instructions and it took me just under 10 minutes from start to finish to install the system - and I have no mechanical knowledge or experience, so if I can do it anyone can. Left the setting on the pre-configured mark and went for a test drive and WOW! Immediate and noticeable increase in power and especially torque. Could not resist tweaking it so increased to the next level and went for another test drive. DOUBLE WOW! I am amazed! I think I shall leave it on this setting - it definitely does not need any more! All in all I can recommend this system - it does exactly what it says it will do and it is a simple 10 minute job to install.

  • Steve from Essex with a Audi A5 3.0 TDI 240 Auto said:

    This is the second car to which I have fitted a Chip Express system, and once again I am absolutely delighted. Engine performance is transformed with a first journey that returned 46MPG over speeds ranging from 40 to motorway speeds. Gear changes are smoother, acceleration fantastic and a general performance that will easily match and exceed any equivalent petrol car on the road. Incredibly easy to fit and once again has proved to be completely hassle free. Having driven diesel cars for the last 25 years, my only regret is that I did not discover this company and what they do until a few years ago. The Chip Express service is second to none. I posted my existing box to them on Thursday and they had it re-programmed and back with me by Saturday morning. So, if your thinking about it, put your worries aside and just get one. You wont regret it!

  • Neil from Nedlands Australia with a Mercedes S320 CDI 235 and C220 CDI 170 said:

    I bought the chips for around town fuel savings. I have just fitted chips to my Mercedes S320 CDI, and C220 CDI, and the results are fantastic. Both vehicles are smoother, and have much more low end torque. They upshift sooner, and hold onto gears longer on inclines. We have reduced our fuel consumption by 10% around town, and by 5% on country runs. Many thanks for your prompt and efficient service, Western Australia is a long way from Hertfordshire!

  • Ian from Manchester with a Audi A6 MK4 3.0 BiTDI 313 said:

    I must say l'm delighted with the improvement from your chip, its on the standard settings and the difference in the car is amazing!!! I have a smile on my face every time I get in the car, and there is about 5-7mpg improvement. With the mileage l do, l can see myself getting my money back in no time at all. So if your a doubter like me, don't be because its one of the best things l've ever bought!!!

  • Len from Seaford, East Sussex with a Ford Focus MK2 2.0 TDCi Auto 136 said:

    I was recommended your chips by a friend so looked at the website and read the reviews. I admit I was a little sceptical of all the glowing reports but decided to buy a chip. I have not been disappointed. It was easy to fit (the hardest part for me was finding out how to remove the engine cover - it just pulls off!) and the car immediately felt different; it was smoother, quieter and the increased performance was impressive. On a recent return run from the south coast to the Midlands I got 61mpg at an average speed of 58mph, a good 20% increase on previous trips. I have very happily recommended your product to other diesel owning friends.

  • Paul from Liverpool with a Ford Kuga MK1 2.0 TDCi 136 said:

    This enigine was already impressive but after fitting the tuning system, it is absolutely brilliant. Torque is more available in higher gears without having to change down and the car itself seems to run smother and quicker. I am also enoying the extra benefits of added MPG! Its win win all round.

  • Dr Mahmoud from Waterford with a BMW E90 320d 177 said:

    Many thanks for your prompt delivery (ordered Friday, received Monday in the Republic of Ireland). May I suggest that you change the name to TORQUE Express! I already had a tuning box which produced a max of 215PS for my E90 320d BMW (177PS). Whilst decent enough, there was considerable piston slap under hard acceleration. The CHIP Express tuning system provided a much quieter and smoother power and torque delivery without fuss! The system is intelligent in the way it soon adapts to your driving style and the way the vehicle is being driven so you do not get the sudden jolt you might get with other boxes under hard acceleration. I am really impressed with the overall performance of my 3-series and I think you set the benchmark for diesel tuning systems. The CHIP Express system is indeed a template for diesel performance enthusiasts. It really is that good. I rest my case!

  • Andrew from Blackpool with a Ford Transit MK7 2.2 TDCi 115 said:

    Just to let you know I am very pleased with my CHIP Express system, my average MPG on the motorway at 70mph has gone from 27-28 MPG upto 32-33 MPG and round town I get about 5-6 MPG more!

  • David from Runcorn with a Ford Kuga MK2 2.0 TDCi 163 said:

    Hi , I recently bought a chip for my KUGA 163 AWD which has totally transformed my vehicle, instantly getting 6mpg more without even altering driving style and all the flat spots have disappeared. I have also joined the KUGA owners club were I have endorsed and recommended your product!

  • Robert from Trefriw with a Jaguar X-Type 2.2D 155 said:

    Box fitted 2 weeks ago. Different car altogether. Will run at much lower revs and still pull away. Have just travelled from north Wales to Portsmouth and back and got 52 MPG at an average speed of 70 MPH. Excellent.

  • Leigh from Taunton with a Mercedes E-Class W212 E250 CDI BlueTEC Facelift 204 said:

    I have a 2015 Mercedes E250 CDI Cabriolet and recently fitted the chip. It took minutes to fit the chip itself and a further few mins of fettling to find the best place to stow the item, all in all a very easy solution. I bought the chip for the extra performance, more torque than power, as opposed to economy gains, and it has delivered it in spades. I took my car out for spin prior to fitting then again on the same road post fitting and I could feel the difference instantly and everywhere. I highly recommend this product for the grin factor, the economy gains will come as a result of the chip which to me is just a bonus.

  • Clive from Canterbury with a Land Rover Defender 2.4 TDCI 122 said:

    First may I say thank you for your efficient and friendly service. I placed my order late on Monday night, then asked for a delivery towards the end of the week; you very kindly acknowledged my request, promising delivery on Thursday, and at about 10:30 this morning (Thurs) it arrived. I managed to wait until just after 11am before I decided to fit it, first moving the car to somewhere better to work, switching off and removing the key and waiting for another five minutes or so. I cheated and left the bonnet open after parking the car, but even so I still think the 3-4 minutes to fit the device was quite good. First nervous switch on, and it just started and idled as normal. So I then tidied the cables using the supplied Velcro strips, put the unit into its pouch and then mounted the pouch on a convenient bracket on the wing. Job done. The first test drive was convincing enough. Mostly country lanes, but the vehicle was very much smoother and altogether much more eager. I'm afraid that this device will make me lazier, as I very soon found that I needed to make far fewer gear changes, even when driving up steep hills. I was much more used to having to work a bit, despite the torque of the excellent Land Rover adaption to an already good Ford engine. Now it seems very much easier. Thank you for an excellent product, brilliant customer service and for giving me a new car again.

  • Tomi from Helsinki, Finland with a BMW 5 Series F10 / F11 520d 184 said:

    Hi! Fitted my tuning box in 10 minutes and went for a test drive. Have to say it was everything you promised! After first acceleration I couldn´t stop smiling! :) Much more responsive car now and the torque is great! I have already recommended your great product! Thanks a lot!

  • Benjamin from Midhurst with a Mercedes B180 CDI 109 said:

    I have just fitted one of your chips to the above vehicle, and I have to say that the improvement to both mid range performance and MPG has been amazing. Both my partner and I just cannot see why Mercedes do not run with these devices as standard. It makes a pretty gutless and dull car so much better. We did not, of course buy this car for its performance, my partner needed an automatic due to her bad knee, however both of us were surprised quite how dull it was to drive. I had known about these devices for some time but had not experienced them 1st hand. I have to say that it transforms the car into just what we want. Money well spent, thank you.

  • Dave from Leatherhead with a Ford Mondeo MK4 2.2 TDCi 175 said:

    I have had the system installed for a couple of days now and am amazed at the difference it makes to the driveability of what was already a very nice car to drive, and economy on my route to work has increased from 40 to 47 mpg. A fantastic product that does exactly what it promises to do.

  • Alan from Whiston with a BMW E60 525d 177 said:

    Just fitted chip set box to my Beemer, very pleased with the result. More power, faster acceleration, pulls a lot better too, just as promised, and all this on the standard setting. Just thought I would let you know and thank you. I will be recommending to others!

  • Yves from Quebec, Canada with a Landini Legend 135 TDI said:

    I am very happy with the chips you provided, the tractors have now been transformed into SUPER MACHINES with much more power and torque, they are now a pleasure to work with! Thank you CHIP Express!

  • Mike from Dumfries with a Massey Ferguson 5465 6.0 R6 120 (VP Pump) said:

    Performance on my MF 5465 with your chip fitted is now excellent, last chip (of unknown make) was only good mid rev range, with poor low and high power delivery. It packed in after 3000hrs. The CHIP Express system provides performance all the way through rev range - absolutely spot on! Very pleased and will recommend this product to others.

  • Doug in Sydney, Australia with a Kia Sportage MK3 2.0 CRDI 184 said:

    In short I have been delighted with the results. The standard program gave a definite increase in smooth torque delivery and power but on the higher settings the car has been utterly transformed. I have every reason to attest to the published performance improvements. The vehicle feels like a V8 now! An effortless surging wave of torque and power throughout the rev range with no increase in fuel consumption. My wife absolutely loves it and will not even consider going back to stock mapping. I cannot recommend this product highly enough. Less than 5 minutes to install, incredible performance increases with no increase in fuel consumption - you'd be crazy not to get this for your Kia. Best wishes from a happy down under customer.

  • Chris from Moreton with a Land Rover Defender TD5 122 said:

    Fitted the unit with no problems using the very easy to follow instructions, first drive and the difference is obvious, vehicle has much more power, pulls better through the gears, making the vehicle a much smoother and enjoyable drive. Less gear changes required as a result in much better torque.

  • Rick from Macclesfield with a Ford Mondeo MK4 2.2 TDCi 175 said:

    Just installed a CHIP Express unit on my Ford Mondeo 2.2 TDCI. All went very well and completed in minutes. The standard setting was impressive and a quick tweak higher, very very impressive. Thank you for your exceptionally rapid response. I am delighted with both the product and the service.

  • Mark from Victoria, Australia with a Ford Focus MK3 2.0 TDCi 163 said:

    Just received my chip for my new 2011 Ford Focus diesel, I am truly impressed by the intelligent reconfiguration of the power curve. Absolutely brilliant low end torque and very linear. Leaving the chip in the standard setting is great, but if you are wanting more BUTA BING BUTA BOOM put the car in sports mode and WOW its fast. I know that there will be greater fuel economy because of the superb low end pulling power which means you do not need to open the throttle as much. Very happy!

  • Reiad from Trinidad and Tobago with a Toyota Hilux MK6 2.5 D-4D 120 said:

    I live in Trinidad and Tobago. I ordered this product for my Hilux 2.5 D-4D. I have installed the device and it works amazingly well. Wish I had bought it years ago! Thank you for such a great product.

  • Andrew from Seaham with a Suzuki Vitara 1.9 DDiS 129 said:

    This is an excellent product. A big thanks to the developers of this chip, it really is better than I'd hoped for. Not only is the turbo lag gone, the Vitara has a new personality which was noticeable almost immediately. It likes to accelerate and the engine is heaps smoother when I put my foot down. I recommend this chip to anybody with the Vitara diesel.

  • Steve from Salisbury with a Mercedes C220 CDI W204 Blue Efficiency 170 said:

    Originally bought this tuning kit for my Mercedes ML280. The difference in torque, acceleration, smoothness and driveability was excellent and immediate. I sold the ML and Bought C220 Blue Efficiency, the same kit that I used for the ML280 was returned to CHIP Express for reprogramming to the C220. It took 48hrs from returning to receiving the replacement and less than 10 minutes to fit, the car has been transformed into the car it should always have been! Excellent service (rare these days), I highly recommend this product!

  • Mark from Penrith with a Toyota Hilux MK7 3.0 D-4D / Facelift / 07-2011 Onwards / Auto / 171 said:

    Fitted in 10 minutes and felt a noticeable increase in torque... if increased driveability and power are required then we are there - straight out the box! Many thanks.

  • Neil from McMahons Point, Australia with a Audi A6 MK3 3.0 TDI 233 said:

    Wanted to thank you for your great service, speedy delivery to Australia and simple easy to understand installation instructions. I fitted the chip to my Audi A6 3.0 TDI Quattro last week and what a difference. Much more responsive, smooth and lightening fast now off the mark. Having done 700klms with the chip is looks as though I have reduced fuel consumption by about 10%. Great work, by the way, my friend bought your unit for his Audi TT 2.0 TDI, wow, what a difference as well!

  • Stefan from Reith bei Seefeld, Austria with a Mazda CX-5 2.2 SKYACTIV-​D 175 said:

    A very simple and clean "installation" - done in 5 minutes with no tools necessary. Smooth increased performance, ideal for when driving in the mountains here. Keep up your great customer service and the excellent product quality!

  • Jeffrey from Co. Antrim with a VW Scirocco 2.0 140 said:

    I recently bought a tuning chip for my 2009 VW Scirocco, the power gains were fantastic and I was very impressed that I could so easily adjust the power setting by myself. This is alone makes Chip Express product unique from any other I have came across! Standard I was getting at best 48mpg but with this box I now achieve over 60mpg! The customer service is brilliant too! I would recommend Chip Express to anyone and already have recommended them to friends and family.

  • Paul from Aldenham with a Land Rover Range Rover Sport (1) 3.0 TDV6 245 said:

    Ordered the chip 4.30pm Friday and it arrived Saturday morning. Could not be happier with the service and my car which now drives so much better! Thanks

  • Alan from Cambridge with a Jaguar XJ 2.7D 207 said:

    Why by one? Why this company? I have a reasonably fast car anyway, what can it do for me? Well after hours of research of almost every supplier in the country and still in doubt I thought I would give it a go. It arrived just 16 hours after I placed the order! Now the real test, what does it do? 600 miles later and a lot of playing with the throttle I can confirm it DOES what it says in every way, loads more initial low RPM power… almost a second off the 0-60 and in kick down you almost have to learn to drive again, especially in the wet! My jaguar XJ now really drives like you expect a Jaguar to drive! Fuel consumption is better too (by about 6/7 mpg) but I am still having fun with the throttle so no real tests. Now that’s why you chip, and that’s why I recommend CHIP Express... brilliant!

  • Terry from Northampton with a BMW 3 Series F30 318d 143 said:

    I found the 318d was cheaper than the 320d with better spec thrown in. The car was ok to drive and lively when I needed it, but I wanted the power of the 320d. The dealer informed me the engine is the same in both models but they're just chipped differently. It got me thinking and my search started for a reputable product to fit to my one year old car. I was a bit nervous but ordered the chip on Friday and was delivered 9am Saturday morning. The photo guidance is really easy to follow and everything just clicked in. I took it for an initial drive round the block on and checked for engine lights or black smoke, but things were good. I've been on two out of town trips since the weekend and not only noticed the extra torque (car will accelerate from 40mph in sixth gear) but my MPG has gone from 52 to 61. The way the car drives has completely changed as the power range, it used to be mostly between 2000 to 3000 revs, and it now drives more like petrol cars I've had with revs going all the way to 5000 without straining. Now when I put it in sport mode it takes off like a bat out of hell! Thank you!

  • Lee from Halifax with a BMW F20 120d 190 said:

    Your customer service, speed at which you deal with questions and chip (most importantly) are second to none. This is the 3rd variation of the chip that I have run, not only do I see the fuel savings made each and every time I fill up but I also feel the changes in the increased performance too. Far too often people only feel the need to leave negative feedback on a product, it's very rare that people take the time to leave positive comments however on this occasion I feel compelled to do so. A brilliant product and one that I highly recommend should you want to make the most of your cars potential performance and make a fuel saving to add into the bargain. What's not to like?! It's been a pleasure dealing with the team at Chip Express, I just wish everyone I dealt with in life was this professional! Thank you.

  • Bryn from Perth, Australia with a Nissan Patrol 3.0 158 said:

    I am amazed with the faultless service you have given me, a service people today seem to have forgotten! Your product is fantastic and many of my friends are now interested in purchasing from you, so I have given them your website and I hope you hear from them soon! Again thank you and your team.

  • Yosa from Thailand with a BMW F25 X3 xDrive 20d 184 said:

    I have received your product with thanks, it only took just 5 minutes to install on my BMW X3 2.0 diesel F25! My first impression is the much improved acceleration. Very happy indeed and thank you for the quick delivery!

  • Earnest from Sydney, Australia with a Land Rover Defender 2.2 TDCI 122 said:

    The chip took just minutes to plug-in using the simple to follow instructions. I started the engine up and took it for a test drive. I felt the difference going uphill straight out of my driveway on route to the main highway, before I knew it I was in sixth gear and cruising along at 75kph at slightly below 1500 RPM. It was like driving a different car. Great product, my money was well spent!

  • Stephen from Essex with a Audi TT 2.0 TDI 170 said:

    Having spent a lot of money on my new TT I was somewhat nervous about fitting the chip. I contacted Chip Express, the technician I spoke to laid my fears to rest, although entirely willing to talk me through the process by phone, as it was raining heavily I declined. The following day and still being a little concerned regarding my technical ability my friend fitted it for me (using the supplied photo instructions). The task was indeed extremely simple and had I pushed my doubts away would have managed with no hassle. It is as simple as CHIP Express tell you it is. So now to the results: Absolutely incredible! I have left mine at the setting supplied and the results are amazing. Throttle is crisp and responsive, gear changes seem smoother. Absolutely no engine lag, mid range it pulls like a steam train, gear changes do indeed arrive sooner and as claimed there is much more speed variance available with no engine labour in the higher gears, so less changing down. Absolutely chuffed to bits. I made the decision to go with a diesel based on economy but now also have the performance of the petrol version. Fantastic!

  • Tim from Tewkesbury with a John Deere 6630 6.8 4V R6 said:

    Fitted first to a John Deere 6630. It transformed this tractor from 125hp up to 157hp. So now have two more on my John Deere 7530s and it takes them to well over the 220hp - all for no extra fuel. Great service from Chip Express - answered my questions before purchasing and sent it out very promptly. Thank you. Everyone should get one, or two!

  • Andrew from Leicester with a Ford Focus MK2 1.8 TDCi 115 said:

    I installed your tuning system into a Ford Focus 1.8TDCi (115PS) after reading all the favourable testimonials. I have to say it did not disappoint... I tested it by driving up to Leeds and back which is a 180 mile round trip for me. I would normally expect about 53-55mpg driving @ around 65-70 mph; with the Chip Express installed I achieved 65MPG! That equates to an improvement of around 20%. Extremely easy to install which took about 10 minutes.

  • Michael from Woking with a Mercedes CLC200 CDI 122 said:

    I am very pleased with the diesel tuning chip, the car is much more responsive and my MPG is better too. I will recommend your products to my friends.

  • Mark from Victoria, Australia with a Audi Q7 3.0 TDI 240 said:

    I currently have one of your chips which we run on an Audi Q7 3.0 V6 TDI. I have had it for approx 12 months or so, the chip is AWESOME, I have left it on the recommended setting, and the torque is incredible!

  • Chris from Coventry with a Land Rover Freelander (2) 2.2 TD4 160 said:

    Received my tuning box today, fitted in minutes then tested it, WOW, absolutely fantastic! Smooth, quiet, awesome torque! Worth every penny, can not wait to tow my caravan with it! Best MPG before was 42MPG, today 52.4MPG. I did not just get a tuning box, I got what feels like a completely new car! Many congratulations on such a superb device.

  • James from Gloucester with a Saab 9-3 1.9 TiD 150 said:

    This chip is amazing, it really did take 5 minutes to fit and what an astounding difference it has made to the car on the recommended settings; however I couldn't just leave it at that, I had to put it to the full bean! BIG DOUBLE WOW!! Awesome performance! My 0-62 mph time has gone from 9 seconds to 6.3 and the power delivery is now just so smooth. Regarding economy, with motorway cruising I'm still getting 62.3 mpg. It’s a shame this system wasn't fitted to all Saab diesels, if it was maybe they would be still going! SILVERTONE TRACK DAY FOLLOW UP: We did not do great due to the pedigree of the competition but without the box fitted I would have given up, I managed to pass a few Porsche Boxster’s and a Golf R32 so was quite impressed! When chatting with other drivers in the paddock they we all stunned that a diesel was keeping up with a lot of them (whilst still managing 27mpg). I absolutely love this tuning system, it’s well made and standing to the test of time, I’m recommending it to everyone I know who owns a diesel! Thanks again for the brilliant bit of kit, it’s worth every penny!

  • David from Train with a Suzuki Grand Vitara 1.9 DDiS 129 said:

    I recently purchased a chip and am pleased to say there has been a significant improvement in performance. The car now feels much more eager, overtakes in places I would not previously have attempted and is much more flexible mid range. Fuel consumption has increased by a few MPG which would probably be more were it not for my driving being more spirited than before. Fitting took about two minutes and I have left chip on the supplied setting. Very impressed!

  • Frank from London with a Fiat Bravo 1.9 Multijet Sport 150 said:

    I purchased the CHIP Express tuning box at 2.30pm Tuesday and received it 11.00am the next morning! I installed the box in under 5 minutes and noticed a immediate increase in performance, much more torque and a smoother ride. The engine sounded quiter and feels free reving, the pick up from absolutely no RPM is just amazing. The aftersales is fantastic, CHIP Express were very helpful with any questions I had. Thank you very much indeed!

  • Michael from Alton with a Peugeot 607 2.2 HDI 170 said:

    I purchased a system for my Peugeot 607 2.2 HDI in May 2010. I would just like to commend you on the tuning chip. I am a private hire driver and cover approximately 75,000 each year. I have no doubt that the tuning chip has saved me 3-4 MPG, and I am now looking forward to achieving similar results on my new Audi A8 3.0 TDI.

  • Ross from Mansfield, Australia with a Ford Ranger MK4 3.0 TDCi 156 said:

    WOW, what a difference! I am half handy-half dangerous and it was absolutely simple to install. Idle is smooth and, as you said, power is noticeably better from 1000rpm onwards, particularly between it's usual range. A gain in both kilowatts and torque is immediately obvious. Engine temperature and behaviour is perfectly normal (it's 30C plus here) and the differences are delivered smoothly and subtlety. One very happy customer!

  • John from Cape Town, South Africa with a Land Rover Defender 2.2 TDCI 122 said:

    Packaging was great and met my expectations and reflected the quality of the product. The instructions were awesome. Pictures were exact, location of the plug precise - it literally took me 5 minutes. Next, the test drive, no warning lights or any abnormalities experienced on start-up. The clutch/ throttle jerk has disappeared almost entirely. Acceleration is smooth and quicker. Revs are available earlier and for longer also assisting with smoother gear shifting. Quieter at higher speeds. Far better pull on the big hills and obviously it’s quite a bit quicker. In a nutshell and bearing in mind it's still early days, I am very satisfied and the tuning chip has delivered bang on expectation.

  • Alan from Darwen with a Volvo XC60 2.0 D3 163 said:

    What a brilliant bit of kit! Once easily fitted I got extra power, a smoother running engine, more miles per gallon and a more relaxed drive due to less frequent gear changing. The system is worth every penny and the customer service is top notch! What more can you ask for?! Thanks CHIP Express!

  • Richard from Kineton with a Mercedes C-Class C250 CDI Blue Efficiency 204 said:

    Just a short note to say thank you. Your customer service is like an oasis in a sea of mediocrity. Nothing is to much trouble - I cannot commend your company highly enough. I have now had one of these chip's well over 5 years on 2 different vehicles. The results on both were great. I initially bought the box for economy but the side effects of smoother delivery of power and more of it were a welcome bonus. I have recommended to friends and colleagues who have bought them too!

  • Alvin from Dagenham with a Lexus IS 220d 177 said:

    One of the only things that let my car down a little was the fuel economy, as well as some hesitation in 1st gear (it would catch me out sometimes at roundabouts). However, thanks to my CHIP Express tuning box both issues are no longer. Acceleration is much improved, smoother and more uniform now but the bonus is the fuel consumption. I'm getting 43-45mpg where before I'd have been getting 33-36mpg. One thing I must say in no small way is that CHIP Express wrote the book on customer service! They responded quickly, patiently and politely to all of my requests for information and support, and I can't speak for anyone else, but that sort of thing means a lot to me.

  • Alf from Cheltenham with a BMW E71 X6 xDrive 35d 286 said:

    Recently bought chip for x6 BMW, fitting was easy and the results were astonishing! Had a chip before in my X5 from another company which gave marginal improvement, yours is so much better I felt I should give you the feedback, (several friends with underpowered diesels have been informed). Regards, Alf.

  • Bryan from Teddington with a VW Golf MK5 2.0 TDI 140 said:

    Just thought I’d drop a few lines of feedback, not sure what use they’ll be, but thanks for a great piece of technology that actually does what it says it will. Supposed to help improve economy as well as power. Well stuff the economy!! It goes like stink now! Tried it on the standard setting, much more responsive. Then tried 2 steps up (1 down from max) and it spins the wheels in 2nd and 3rd. So dropped it down one peg and perfect. No wheel spinning, but pulls like a train. Speeding ticket, here I come!!

  • Paul from Perth with a Nissan Pathfinder 2.5 dCi 190 and Isuzu Rodeo 3.0 130 said:

    Just wanted to let you know that I am very very happy with the chips I bought from your online store a couple of months ago. I have the new 2010 Pathfinder and power is defiinately right up, economy is better and I love the car now. Tows much better and goes like it should. My Rodeo is also a dream to drive now and fuel consumption is perfect. Thanks very much!

  • Juhani from Lapland with a Ford Transit Connect 1.8 TDDI 75 said:

    Thank you for your digital module which arrived in Finland (Lapland) last week, the power increase is substantial, I am now faster than the reindeers finally!

  • Jim from Tayside with a Land Rover Range Rover (3) TDV8 3.6 272 said:

    Fitted a CHIP Express module to my TDV8 last week... WOW!!! What a difference... the lift from standstill is fantastic almost makes me forget how good the Audi S8 was... a cinch to fit, even I managed to plug it in which is amazing considering how useless I am mechanically. I have never been very sure about these after market devices that promise amazing results but have to say that so far I'm impressed... My real time MPG was averaging 18.9 before and now that has risen to bang on 21 which admittedly is not a huge saving but to get even a small increase in MPG for such a large increase in performance has definitely made the initial outlay worthwhile and I suppose makes this one of my better decisions.

  • Kani from Istambul, Turkey with a BMW E84 X1 xDrive 20d 177 said:

    I was really disappointed with my 2011 model 177ps BMW X1, I was beginning to miss the performance on my old BMW Z4. I decided to order one of your systems. I fitted the system within 10 minutes, fitting was easy and the installation was tidy. However the real surprise was in the drive, now with the CHIP Express fitted I get similar acceleration to my Z4! Thank you.

  • Steve from Sussex with a Volvo XC90 2.4 D5 200 said:

    Ordered at 3.30pm and it arrived and was fitted by 10.30am the following morning. Fitting was simplicity itself and could not have been easier. Have not driven it far yet but there is a noticeable increase in power but more importantly loads more low down torque for drivability. BRILLIANT and much better value and better increases than Volvos own Polestar chip! FOLLOW UP: Further to my earlier posting I have now had more opportunity to drive the car since fitting the CHIP Express box. The car is noticeably smoother, and the increase in torque not only provided better drivability but the auto box now changes down sooner on demand and up into top gear earlier on light throttle. This has resulted in an indicated increase in fuel economy, I am now getting 470 miles to a tank as apposed to 400 before fitting the box. Absolutely delighted!

  • Tony from Hitchin with a Toyota Land Cruiser 3.0 D-4D 163 said:

    The Land Cruiser is now much smoother to drive and faster when needed, but best of all I have improved fuel economy. I was getting around 28mpg but now get 32mpg, so up from 415 miles per tank to around 450 miles per tank. A great product!

  • Simon from Sherfield-on-Loddon with a Ford Focus MK1 1.8 TDDi 90 said:

    I have today received the chip and installed it as per instructions. I have to admit that I was sceptical that this little box would be any use for improving my vehicle because of her age and the fact that the current mileage 186,000, but WOW, what a difference it has made, it's like she's brand new again, lots of torque and really smooth power delivery. I am impressed, thank you for giving her a new lease of life!

  • Dave from Coulderton with a Fiat Ducato 2.3 Multijet 100 (Motorhome) said:

    The chip on my 100 Multijet worked wonders. The 100 engine was just that bit small for the motor home but with the chip fitted it made so much difference. It enabled us to cruise comfortably at about 70mph and fuel consumption was better!

  • Simon from Long Crendon with a DAF CF 5.9 185 said:

    More responsive from the off on first impressions. I only did a quick run on standard settings and then on full power. No black smoke to be seen either which is a bonus. Many many thanks for your help and support, it is very refreshing to have such good service and good will from a company and it is very much appreciated. I will have a good run with the vehicle later in the week. FOLLOW UP: Had a chance to drive my tanker with a load on and I am chuffed to bits with it, goes like a rocket. Big thumbs up from me!

  • John from Blairgowrie with a Nissan Navara MK2 2.5 dCi 171 said:

    Just a note to say how deligted I am with my purchase. I have a Nissan Navara 2.5 dCi and the difference in performance is quite phenomenal. My MPG has gone up from 26 to 34, and the improved acceleration very noticeable. Does what it says on the box, excellent piece of kit!

  • Stuart from Ayr with a BMW E63 635d 286 said:

    Just had 2 years of a CHIP Express system in my BMW 635d M Sport - massive improvement in general response, smoothness and performance. Fuel economy maintained. Just upgraded to 640d - planning to fit unit to replacement car. Also experience with unit fitted to BMW X1 xDrive: same fantastic effect - just generally better to drive and more responsive. Service from the CHIP Express team has been superb. Units are high quality and very easy to fit. I have no hesitation is recommending the company and product.

  • Glenn from Saundersfoot with a Mazda CX-7 2.2D 173 said:

    The chip arrived the next day and was easy to fit after following the instructions. Although there was a difference on the standard setting after "tweaking" or fine tuning the car has all the performance I require. The increase in power especially midrange in 4th/5th and even 6th gear is considerable. As to saving fuel, I'm enjoying the increase in power at the moment, but I can see that I will not have to keep changing down so much. Cheers!

  • Peter from Keighley with a BMW 5 Series F10 530d 245 said:

    Thanks CHIP Express, you've done it again! I have been using your chips since 2008. First on an Audi A6 2.7 TDI, which increased my MPG from 37 to 40 together with a marked improvement in power delivery. When I changed cars to an Audi A8 3.0 TDI, you reprogrammed the old chip for very sensible money and once again improved power output and my MPG. I have been so satisfied with the service provided that, when I changed again to a BMW 530d, my first port of call was to yourselves and you have not let me down. From contacting you and you returning the new chip took 5 days, and within 5 minutes this was installed. I can report that over the last week I am starting to get an increased MPG. I cannot recommend your company too highly. First class product, first class service. A pleasure to deal with. Anyone thinking of improving their MPG and power output in these harsh economic times would be well advised to consider CHIP Express before many other alternatives.

  • Martin from Verwood with a Land Rover Freelander (2) 2.2 TD4 160 said:

    I have fitted your unit and just come back from a short drive, WOW, it is smoother, more responsive and also faster. Just what I had hoped, fitting was straight forward due to excellent instructions and photos. I look forward to driving my Freelander to Birmingham on Saturday. Thank you for the prompt delivery!

  • Chris from Bideford with a Ford Mondeo MK3 2.2 TDCi 155 said:

    Fitted without a problem and noticed an immediate improvement in performance and economy. My fuel economy went from an average of about 43mpg to about 53mpg and has been as high as 56.1mpg (at best). The drivability has been noticeably better too!

  • Mark from Rushmere St Andrew with a Ford Kuga MK2 2.0 TDCi 163 said:

    I ordered my chip for my 2012 Ford Kuga late afternoon on Tuesday and it was with me before midday Wednesday! Fitted it in minutes yesterday without a hitch. Test drive revealed instantly noticeable improvements in performance, particularly torque increase. Could have left it at that and would have been more than satisfied but I decided to tweak it up a notch following the clear instructions and again this was achieved in a minute or two. Another test drive and again there was a noticeable increase in power and torque with no adverse side effects. Very pleased with the product and service and I would thoroughly recommend going for it if anyone is thinking about it.

  • Rod from Los Angeles, USA with a BMW 3 Series E90 335d 269 said:

    I ordered the chip thinking that the claims made in prior testimonials could not live up to the hype. Boy, was I wrong! This chip delivers just as advertised, I could not be more pleased. I am so pleased, that I am ordering another for my 2012 BMW X5 35d and telling anyone that will listen to get their very own.

  • James from Eyemouth with a VW Sharan MK2 2.0 TDI DSG 170 said:

    I have had my Chip Express unit installed for 1 week now and would just like to let you know that I am extremely happy with it. It took minutes to fit to my brand new VW Sharan. The main reason for buying it was to improve fuel economy. On the twice daily 24 mile school run MPG has increased from 36 to 44 and on longer journeys it has increased from 42 to 50 MPG. Nothing short of remarkable for a large, heavy, 7 seater car. The increased performance is handy for quick overtaking, and can it quite easily outrun many "sports saloons". I can highly recommend your product, IT REALLY DOES WHAT IT SAYS ON THE TIN!

  • Paul from Sydney, Australia with a VW Amarok 2.0 BiTDI 163 said:

    Since I installed the chip into my Amarok I have seen a big drop in the fuel consumption and a noticeable increase in power. I run the car loaded with my tools so it is always carrying a fair amount of weight. I am very pleased with my investment and would recommend it!

  • Andrew from Kaiapoi, New Zealand with a Toyota Hilux MK7 3.0 D-4D 171 Auto said:

    A great product, it took just 5 working days to reach the South Island of New Zealand. Easy install and my 2013 Hilux 4WD was away with great results as advertised, straight out if the box! A very marked difference in acceleration and top end, acceleration at speeds over 120kph was very good. So a big "thumbs up" and thanks to all the team there!

  • David from Casar, USA with a Dodge Ram 3.0 EcoDiesel 243 said:

    I am greatly pleased with my chip on my 2015 Ram V6 EcoDiesel. I am getting 20% more fuel mileage. Traveling on the road was the reason for buying the chip, I was not looking for more torque or horsepower but economy. The truth is we go both. I am completely satisfied with this product.

  • Mark from Thame with a BMW E70 X5 40d 306 said:

    I have just fitted your chip to my new BMW X5 40d and I wanted to let you know how pleased I am with the results. It's like driving a different car! Smoother, more power and faster acceleration, just as promised, and all this on the standard setting. I will be recommending this to others!

  • Richard from Tavistock with a VW Tiguan MK1 2.0 TDI BlueMotion 184 said:

    I raved about this unit on my Golf GTD back in 2013 and since then have transferred it to a Touareg 3.0 TDI with similar results. Now it is going on to a 3rd vehicle a 2.0 TDI Tiguan. Throughout any query or guidance I have needed CHIP Express have been there to help, whats more they do so quickly. Initially the cost may daunt but thinking of it long term, it pales into insignificance. A classy product from a reliable supplier. No I am not one for rave reviews but this time I felt I needed to. FOLLOW UP: Completed installation of remapped box on Tiguan and went on extended test run. Not really necessary as the greatly refined running and increased smooth power was clearly evident in the first half mile. It brings the car alive!

  • Peter from Falmouth with a Renault Scenic II 1.9 dCi 130 said:

    I'd had my Renault Scenic DCi 130 for 3 years and was getting fed up with its performance and general sluggishness. Got the tuning box from your good selves, fitted it in the dark in about 10 min. What a difference! Makes me smile just thinking back to that first drive. The box has been on the car for about 3 months so far. Economy is up by around 15%. General driveability is excellent on standard setting, mid-range punch is a revelation.

  • Simon from Hamiltonsbawn with a BMW F10 525d 204 said:

    I recently purchased a chip for my 2011 525d. Instructions for fitting were specific for my car. Now fitted you can really feel the difference. Everything is much snappier and power delivery is very linear. This is an excellent system. I have covered about 3000 miles with this chip and on my 48 mile run to work (a mix motorway and A roads) I get 47 mpg. This obviously drops when my right foot gets too heavy but it is nice to know I have the option to save fuel or save time. Would definitely recommend.

  • Rod from Wickford with a Mercedes ML350 CDI 231 Blue Efficiency said:

    I purchased my chip unit in September 2009 primarily for the increase in torque it gives for towing our then new caravan. It was a revelation! Not only did it make for a safer more comfortable drive, the extra fuel economy is very handy when towing. Clearly, when not towing the difference in power and fuel economy is even more impressive. Initial acceleration has a much better response, crisper, sharper again making for a safer vehicle, particularly when exiting round a bouts in the busy periods of high traffic volumes. Powering on (there safe to do so) is remarkable, coupled with the huge difference in the mid range it makes for a true sporting experience. Such has been my experience over the last 5 years that I have had the chip re-programmed by CHIP Express, who I have to say have been really excellent and very efficient with the service, and with the new leads and instructions supplied I will be fitting to our 2011 ML350 Blue Efficiency very shortly. Whilst a more powerful V6 231 bhp CDI engine, I expect, relatively speaking, a similar transformation and experience. Thank you!

  • Ugur from Turkey with a Fiat Bravo 1.6 Multijet 105 said:

    I received my order on Monday this week and fitted it to my 2009 Fiat Bravo 1.6 Multijet. The result is amazing! I am absolutely satisfied with the product. I think every conscious diesel engine owner should try Chip Express and experience it for themselves. Thank you for manufacturing such a little miracle.

  • Dave from Hainaut, Canada with a BMW F10 520d 184 said:

    Installed the tuning module last week and I am extremely pleased with the results. Prior to installation I enjoyed driving my car, but now I really love driving the car. Makes me wonder why anyone would spend 11000 more to purchase a 530D. During the past week I tried the various settings and have had positive results with all levels. Fuel economy has only improved approximately two percent at highest setting, probably because the increased power entices me to drive more quickly. Recommended for the F10 520D!

  • Steven from Antrim with a Vauxhall Frontera 2.2 DTI 115 said:

    Just wanted to pass on my thanks, Chip Express is a fantastic product! I used to loathe driving my Frontera, but now I love it, I can not wait to get driving it. The formerly gutless motor now has power and torque I didn’t know it was even capable of producing. Driveability has increased 10 fold, the pre-chipped motor only had a small amount of power between 2000- 3000 rpm and just had no power past 3000rpm, now with Chip Express it pulls like a train right the way through the rev range up to 5000rpm limit, and the low-down torque is unbelievable! Fitting was simple and took 5 minutes, no problem. Fuel economy has definitely improved, although I have not quite worked out exact figures yet, but I will get to that. Another thing is that the engine now sounds and runs perfectly, it’s very smooth, even on idle. I will be recommending your product to everyone I know with a diesel car, I am just sooo impressed with this product. Thanks again guys!

    After a very simple and easy fit (two weeks and around 2000Km later) I can only say how happy and surprised I am with the results I have experienced from your product. The performance increase feels to be in line with the figures you quote and the fuel economy so far works out to be around a 12-14% improvement over the non fitted figure. As a result of this I would highly recommend your product to anyone that may be contemplating an upgrade for their diesel!

  • Henry from Tauranga New Zealand with a Holden / Chevrolet Cruze 2.0 VCDI 150 said:

    I installed my "chip" three months ago. The car's performance has improved markedly with no turbo lag at roundabouts etc.. A great car, and now a powerful motor!

  • Matt from Filderstadt, Germany with a BMW E90 335d 286 said:

    I bought the CHIP Express diesel tuner for my BMW 335d Touring 5 months ago. The car performs flawlessly on the Autobahn here in Germany. The tires now break traction under hard acceleration if provoked, its great! I will always recommend your product. Tschüß.

  • Andrew from Baulkham Hills, Australia with a Volvo XC60 2.4 D5 215 said:

    This chip has totally changed the dynamics of my Volvo XC60 in normal DRIVE mode with incredible performance in SPORTS mode. The pickup and smoothness in acceleration is rather amazing. My wife couldn't believe the difference. Very easy to install. Don't hesitate in buying from CHIP Express the results are worth the investment.

  • Joe from Fairfield, Australia with a Holden Cruze 2.0 VCDI 163 said:

    I received my Chip Express a few days ago and installed it today and all I can say is WOW! I can feel a huge difference in torque and performance, and my Holden Cruze actually drives alot smoother now. I can barely feel the engine revs on my foot. Great work and a great product!

  • Ray from Tavistock with a Porsche Cayenne MK2 3.0 Diesel 245 said:

    Ordered a chip for my new Porsche Cayenne yesterday and it got delivered the next morning! Fitting the chip was absolutely simple and the instructions were there if required. Just had a test drive and first impressions are very impressive - I suspect it will not help my 21" tyres or licence but you cant have it all! Thanks!

  • James from High Peak with a Skoda Yeti 2.0 TDI CR 140 said:

    Fitted the chip to my Skoda Yeti 2.0 TDI about nine months ago, it does exactly as you describe. It roughly saves me about £100 every 5,000 miles and the difference in power and torque is quite amazing and instantly noticeable, its not often a product meets my expectations. Thank you!

  • Martin from Peterborough with a Vauxhall Astra J 2.0 CDTI 165 said:

    I purchased a CHIP Express for my new 2012 Vauxhall Astra SRI 2.0 CDTi. Well what can I say? What an improvement from just adding the chip! It has improved all what it says on the box. I've just increased the power to max and I am still getting 48mpg. I would really recommend these chips to anyone who has a diesel. The power and torque is such an improvement over standard!

  • Alan from Argyll with a Skoda Superb MK2 2.0 TDI CR 140 said:

    My second system from you, so impressed with the first, 10mpg+ increase in average fuel consumption, with motorway cruising at 61mpg (up from 48mpg), added power is a brilliant bonus!

  • Tony from Malanda, Australia with a Holden Rodeo 3.0L Common Rail 163 said:

    Would like to add comment on my Chip for my 2007 Common Rail Holden Rodeo 4JJ1 after a 700km trial run with the Chip. Instructions and fitting were simple to follow and easy, took less than 20 minutes. My car had done 125k prior to fitment. I found noticeable increase in torque which is great in the Rodeo for hill starts in first gear. There is a very noticeable increase in performance in the hilly country, with much less gearshifts needed. The car was able to maintain 110kph (fully loaded GVM 2900KG) a lot easier with noticeably smoother engine performance. Fuel consumption was 1ltr per 100k better, outstanding considering I was driving the car hard to find the full potential of the Chip. I would recommend your product.

  • Rod from Farnborough with a Skoda Octavia MK2 1.9 TDI 105 said:

    Sirs, I am delighted with the chip fitted to my Skoda Octavia, 4 cyl, 8 valve, 1898cc. The difference in torque is very noticeable. Thank you!

  • Wolfgang from Ontario, Canada with a VW Golf MK6 2.0 TDI 140 said:

    Had my CHIP Express hardware now for about 9 month and love it. I drive a 2.0L TDI Golf Wagon (2010) in Canada and installed the chip in under 10 minutes. The HP and torque increased instantly after installation. The engine sounds a little bit different, however It appears to sound better. My gas (diesel) mileage increased by over 10%. I used to cruise with an average mileage of 5.4 L/100km, thanks to CHIP Express this has improved to about 4.7 L/100km. I ended up increasing the output by two notches (settable on the control unit), I could feel the increase. Great Product, easy to install and easy to remove for VW Maintenance Service. I would highly recommend the Chip Express for the fuel savings or for the increased power.

  • Paul from Wisbech with a Ford Ranger MK5 2.2 TDCi 150 said:

    Thank you for sending out the chip for our 2012 Ford Ranger, initially I found the truck to be very under powered but after installing your chip it made a substantial difference. Pulling power increased though all gears and made it a joy to drive! This is the second chip I have bought from you which says it all really!

  • David from Liverpool with a BMW F10 M550d 381 said:

    Feedback to say that I am more than happy with the increased performance and economy from the tuning. Fuel costs are very important but so is arriving on time to a meeting. My son Mark first introduced me to the possibility with my BMW 525d xDrive. Since then we have used this system on the two BMW 320d xDrive's and the BMW 740d xDrive. I recently part-exchanged the BMW 740d for a BMW M550d triturbo. The benefits pay for the system in a short time and then it is a win-win situation: A win with more performance and a win with more economy! FOLLOW UP: I am very happy with the results. The high speed response is far better. Thank you very much for the upgrade!

  • Lee from Halifax with a VW Golf MK7 2.0 TDI 184 said:

    I have been running the chip for a couple of thousand miles and I'm getting great results. Economy on the whole is about 7-8 miles more than without the chip. VW's figures leave allot to be desired! Currently running at around 52mpg combined and the performance on what was already a quick car is incredible! Even in Eco mode the pick up is amazing. All in all the chip is brilliant and I would recommend the chip to anyone looking to make gains in both mpg and performance.

  • Steven from Melvourne, Australia with a BMW F10 520D 184 said:

    I have just installed mine in a 2012 BMW 520D with outstanding power improvements. Specifically it got rid of the turbo lag, which in my opinion I thought was dangerous. The CHIP Express kit has made the car better to drive and more importantly safer. BMW, you should take note of this system for future car releases!

  • Darren from Sheffield with a Kia Ceed 1.6 CRDI 115 said:

    Just bought a chip for my kia Ceed diesel automatic, a 2008 model. I have just done a comparison test before and after. Throttle is now much sharper the engine is smoother, the turbo seems to carry on giving stronger boost further up the rev range. I did a 10 mile round trip-before the chip, average 50.1mpg, after the chip average 56.3 mpg. I now have a smoother, faster and more economical cruiser. Thanks from a happy customer!

  • Dave from Carmarthen with a Skoda Yeti 2.0 TDI CR 110 said:

    This is the second time I have fitted the Chip Express to one my cars. The first was to my BMW 118d 140PS which after fitting went to 170PS. Not only did I have the power and torque to overtake (especially on hills), but the MPG went from 54mpg to 62mpg. I now have a Skoda Yeti 110PS which I have just fitted the Chip Express too, the difference is mind blowing! It takes it from 110PS - to 140PS. It also has improved the economy from 54mpg - to 68mpg! Very happy!

  • David from Leicester with a VW Touran 2.0 TDI CR 170 said:

    I have a Touran 2.0TDi 170 (2012). I have used 'fuel chips' in the past with varying success. However, once I fitted the Chip Express module I was quite frankly gob-smacked! Using the optimum setting I have gone from 168bhp to 198bhp (ish) and I am now comfortably returning 60-65mpg with normal driving. The power delivery is considerably smoother and over a much wider band. All in all, it's a 10/10 for me, an absolute no-brainer in terms of money saved on fuel costs over 3 years - even at 10k miles per annum. All that combined with good customer service provided by people who clearly understand their product makes this one of the better purchases I have made.

  • George from Nairobi, Kenya with a Toyota Land Cruiser 4.2 TD Amazon 204 said:

    I run two of these vehicles, now both tuned with the CHIP Express system, they run like a dream on the supplied settings with much more bottom end torque, this makes for a much more refined delivery of performance and makes the Cruiser much more manageable, especially at lower speeds when off road. Economy is also slightly better too which is unbelievable give the transformation of the drive, thanks again for all your help!

  • Mark from Godalming with a BMW E90 318d 143 said:

    Just wanted to write in to thank you for a fantastic product which increased the drivability, power and efficiency of my new BMW 3 series and gives me the same power as the next model up! A great 'plug and play' product which can be fitted and removed in a couple of minutes. I was concerned that it wasn't going to work but I shouldn't have worried. Couldn't recommend your product enough as well as your excellent customer service.

  • Frazer from Gwent with a Vauxhall Insignia 2.0 CDTI EcoFLEX 130 said:

    I have had my Chip Express fitted for about 6 months now to my Insignia 130ps EcoFLEX. Instant power increase and getting on average 56 miles to the gallon even with my heavy right foot!! I have been meaning to play around with the fine tuning settings for a while but only just got round to it yesterday. MY GOD what an even bigger difference... the car pulls like a freight train in 5th and 6th gears now and acceleration in 3rd and 4th is awesome!!! No extra smoke or soot and runs really smooth still. Thanks Frazer

  • David from Coaley with a Audi A6 MK2 2.5 TDI 180 said:

    The chip arrived the next day and was an easy fit - great instructions. I wrote to you before buying as I was keen to improve economy… anyway, economy is around 38mpg, up from 31.8, so good news! The car pulls really well and changes up much sooner through the gears - perfect.

  • Geoff from Kidderminster with a Audi A6 MK3 3.0 TDI 240 said:

    I bought one of your chips for my A6 3.0 TDI Quattro. I am delighted so far with the difference, I only purchased it for the fuel economy. Urban has increased from 25 mpg to between 30 and 31 mpg. On a motorway trip of 110 miles the car returned 45 mpg although this is usually late thirtys rather than in the fourtys. Thank you great product.

  • Jim from Ontario, Canada with a Mercedes X164 GL350 CDI BlueTEC 211 said:

    My compliments! I've just installed the Chip Express on my 2012 Mercedes GL 350 Bluetec. The chip is connected correctly and operation is obvious the first time you use the throttle. Thank you for creating such a terrific product, I am very impressed! I will certainly promote your product to everyone here in Canada.

  • Mark from Credigion with a Fiat Qubo 1.3 Multijet 75 said:

    It's been about a month since I purchased a chip from you. I can say performance has improved and driving has become more relaxed due to this product. I haven't played around with other settings and will probably leave it as set by yourselves, but overall I am more than impressed!

  • Ken from Bethania, Australia with a Land Rover Discovery (2) 2.5 TD5 138 said:

    I like your instructions, very easy to follow and what a difference, a different vehicle altogether! I can't wait to go on a long trip towing my caravan. Once again thank you for your great service, I would have no reservations about recommending your product and service to anybody considering this type of upgrade.

  • David from Bridge Of Weir with a Audi Q5 2.0 TDI 170 said:

    Firstly, delivery was absolutely on the button, and within 24 hours of placing the order online, my Audi Q5 was chipped. The fitting procedure was phenomenally simple, and the results were immediately apparent. My fuel economy has drastically improved, from high 30's to mid 40's. Absolutely delighted. New car arrives in November, and the first purchase will be another chip!

  • Matt from Kinnesswood with a Land Rover Freelander (2) TD4 150 said:

    I am now driving a different Freelander thanks to CHIP Express, 5 mpg better economy and perky in all the gears, I feel confident at passing other vehicles now!

  • Michael from Cleveland, Australia with a Ford Ranger MK5 3.2 Facelift 200 said:

    Had some time to myself this morning and got the chip installed - immediate smile as the annoying initial turbo lag under acceleration was considerably reduced. This was my major bugbear with this engine and primary reason for searching for 'fixes'. Strong, much more linear power flow with the lower gears seeming to 'hold' that fraction longer - a considerably better output than standard. The whole acceleration process just feels smoother and less constrained, more like my V-6 petrol Hilux! FOLLOW UP: Dropped in on an acquaintance with the same vehicle (tho 6 months older and about 12k on the clock), he took it for a drive and immediately recognised a big difference (favourable) from his stock version - I then took his to remind myself of what my vehicle drove like only just over a week ago. I'm extremely happy with what your chip has done for the drivability of my vehicle!

  • Davie from Aberdeen with a Toyota Hilux MK7 3.0 D-4D / Facelift / 07-2011 Onwards / Auto / 171 said:

    I purchased my 62 plate Hilux Invincible last week and drove it from Birmingham to Aberdeen. I was very pleased with the performance and the fuel economy averaged 32mpg at 70mph. Purchased a Chip Express tuning box and fitted it earlier today and took the truck for a run on the setting supplied. The difference was instantly noticeable. I then raised the setting even higher and I cannot believe the difference! It has an awful lot more power and hangs on to top gear for a lot longer but the best part is that the MPG has gone right up to 37mpg at 70mph. Thoroughly recommend this to be fitted to any Hilux. Should have come from the factory like this as standard as it has totally changed a great truck to an even greater truck to drive, thanks to the guys at Chip Express!

  • Steve from Torquay with a VW Amarok 2.0 BiTDI 163 said:

    I have been using your chip for just under two years and have been delighted with the performance difference, fuel economy is 10-15% better and I need to change gear far less as third gear was made much more wide ranging. Importantly I am able to tow a twin axle caravan with ease and at 65mph I get the same MPG as my old Hilux did without a caravan on the back! I recently decided to change my model of Amarok to the BiTDI 8 speed Auto and so before heading off on a long round trip to view a possible vehicle I decided to remove the CHIP Express unit. The result was that it was like driving a different vehicle with much reduced performance and fuel figures. I have since returned my chip for reprogramming to suit the BiTDI. Thank you for an excellent product that definitely meets and surpasses your claims.

  • Stephen from Brackley with a Mitsubishi L200 / Triton MK5 2.5 Di-D 136 said:

    I am impressed with the chip I purchased. Before fitting power at low revs was flat and left you thinking come on! However as soon as I pulled out the drive after fitting I could feel the difference. Now its responsive at any revs and so much nicer to drive, in fact at higher revs its more like my BMW X5. Thanks for putting a smile on my face, it is nice to buy something that does exactly what it promises.

  • Urs from Brisbane, Australia with a Ford Ranger MK5 2.2 TDCi 150 said:

    I just wanted to report that I am a happy customer, I have had your product for over a year and although I don’t use the car much last weekend I did 260km on the freeway and averaged 6.8litres/100km, I also found the car runs much smoother. I have recommended CHIP Express to many of my friends and other Ford enthusiasts, thanks again for a great product!

  • David from Tenbury Wells with a Mercedes Vito 122 3.0 CDI 224 said:

    A few years ago I purchased a CHIP Express unit for my Vito 120, I recently had it transferred to my 2012 Vito 122 and it works perfectly, this new vehicle has a trip computer and I was very happy to find that even though I have loads of power for overtaking I can still achieve 30+ MPG when I'm not in a hurry!

  • Randolph from London with a Audi Q5 2.0 TDI 177 said:

    Covered 1800 miles prior to fitting the CHIP Express. Installation procedure very straightforward. First impressions, engine noise is decreased and appreciable improved low down torque. Tested it in different Driver Select programme modes from Efficiency thought to Dynamic. Certainly, urban (around town) commuting will benefit from using less throttle for increased power output resulting in improved economy. Tempted to try higher power engine modes, but for the time being supplied settings suffice. Fast delivery as indicated on website, clear instructions, supportive helpdesk.

  • Alan from Downham Market with a Mitsubishi Outlander 2.2 DI-D 150 said:

    After being a very happy customer purchasing a tuning module for my old VW Touran, I am now just as pleased with having a second tuning module for my new Mitsubishi GX3 Outlander. It transforms the car into a much smoother drive with improved MPG! It's been a pleasure to deal with a company who can give you good advice, and if I decide to change my make of car in the future I would not hesitate to contact CHIP Express!

  • Michael from Tullnerbach, Austria with a Jaguar XF MK1 3.0D Edition 211 said:

    I received the tuning box this Monday (excellent service). After installation everything worked perfectly as expected. The new found power is just great. Everybody should try it! Thanks again!

  • David from Romford with a Audi A3 MK3 1.6 TDI 110 said:

    I just wanted to drop a few words to say how impressed I am with the Chip Express for my A3. My main reason for getting it was to eliminate the various flat spots I had throughout the gear and rev range. This has been completely eliminated and for an auto is a lot more responsive than before. The fitting instructions were very well set out, which made installation a ten minute job. I cannot fault the chip and would definitely recommend it. Another plus to is the outstanding customer service you offer as a company, and in this cut throat world we live in, it is a welcome change to the norm. Keep up the good work guys and thank you very much.

  • Anthony from Dorchester with a Mini 2nd Gen. 2.0 SD 143 said:

    I have fitted the Chip Express unit and carried out a 250 mile drive to the film location at which I have been working. Having driven this same route a couple of times last week I was able to make a fair comparison, the difference was outstanding! The engine is smoother and develops much more power when required whilst still returning improved economy. This is my fifth chip and my third successful upgrade on a Mini Cooper Countryman ALL4, the first on the 2.0 D Auto 112, the other on a 1.6D 112. I cannot praise this device or Chip Express enough!

  • Peter from Chippenham with a VW Tiguan MK1 2.0 TDI DSG 140 said:

    The addition of your digital add-on has made a marked difference to performance. I have not altered the settings as, for me, the extra power when I need it is perfectly adequate, for the time being! What is especially surprising (being a cynic) is that the claim it will improve fuel efficiency is actually true! I noticed within a very short distance that fuel consumption was showing a big improvement, from an original average of 41 mpg to 45.7 mpg. . . . and that's just local driving - I haven't been on a run yet! The extra power also puts a smile on my face. Am I happy? Big yes!

  • Simon from Leicester with a Nissan Navara MK2 2.5 dCi 174 said:

    Fitted the chip tuning system today, it has totally transformed the truck, as well as being much faster in general it is also unexpectedly much smoother. The well known torque holes have also disappeared and the auto box kick down now responds how I feel it should, thanks guys!

  • Les from Salisbury with a Fiat Ducato 2.3 Multijet 130 said:

    We bought a chip for our Fiat Ducato X250 motorhome in 2011 and were impressed with the much improved torque and economy. We had some very long trips, e.g. all the way to Sicily and back, with no problems. In 2013 we transferred the module to a new Ducato X250, with the same improvements. The vehicle does a steady 31 mpg and is a pleasure to drive. Recently a fault arose and as a precaution we got CHIP Express to test the module. Nothing wrong with it. Excellent customer service (which is a lot more than I can say for Fiat!).

  • David from Duns with a BMW F10 535d GT 299 said:

    Useful improvement in economy of around 10% on shorter journeys, this becomes more like 17-20% on longer trips. I also used the system on a Seat Ibiza 2.0 TDI CR 143 which also resulted in much improved engine response and economy. This is an excellent product!

  • Paul from Wisbech with a Land Rover Freelander (2) SD4 190 said:

    I would like to thank you for your service in regards to my Freelander 2 SD4, I have found the response is just as you said, it has made it more active on pull away, whilst increasing the available power, the difference excellent. Installation was a breeze, would 100% recommend this chip, your customer service is excellent, thank you once again.

  • Steve from Port Augusta, Australia with a Mazda BT-50 MK1 3.0D 156 said:

    Fitted the power chip today, well I am converted! Standard settings as supplied were perfect, lots of low end grunt for towing, great midrange which extends beyond what you actually need. No more turbo lag, now super responsive from 1000 rpm, this is much better for moving trailers or retrieving boats etc, the clutch no longer needs to be slipped to get rpm up to pull the load initially. This is the best upgrade I have done on any vehicle, money well spent! Please submit my feedback so others may benefit. Thanks for such a great product!

  • Ross from Winshaw with a Renault Laguna III 2.0 dCi 177 said:

    I would like to thank you for the excellent service. The difference in performance was massive, my Laguna GT 180 was transformed; I could stay in higher gears at low revs and accelerate much more quickly. I really noticed the difference when I removed the tuning box to sell the car, it felt flat without it. I sent the tuning box back for an upgrade to my new Kia Sportage 2.0 CRDI 136, which is also superb. Turnaround was only a couple of days. The customer service is excellent, I would highly recommend CHIP Express!

  • Stuart from Langport with a Iveco Daily MK4 3.0 HPT 177 and VW Transporter 2.0 TDI 140 said:

    I have bought two tuning chips, one for an Iveco Daily the other for a VW Transporter. I have been very impressed! Both vehicles are achieving around 10% more miles per gallon and producing a lot more power thus improving the drive no end, 10 out 10!

  • Stephen from Woombye, Australia with a Nissan Navara MK1 3.0 DI 150 (AU Spec) said:

    I just installed my new diesel performance tuning chip, I must say I am impressed by the low down torque through the gears and revs out so much quicker making the Navarra a breeze to drive. Can’t wait to put my 2 ton caravan on the back to see how it pulls. Thanks heaps!

  • Adrian from Tolmie, Australia with a Nissan Patrol 3.0 DI 160 said:

    Installed a chip on my 2006 GU Patrol 118kW. Power difference is very noticeable, a lot more power down low in the revs, worth getting just for the performance gain! Cheers!

  • David from Cambridge with a Rover 75 2.0 CDTI 131 said:

    Bought this chip last year, it completely improved the way the car drove, it was a different car! I am very happy with my purchase and your service, thanks!

  • Roger from Lancing with a Ford C-Max MK2 2.0 TDCi 163 said:

    Fitted the chip one week ago, a great improvement, I have the Powershift automatic and gears now change up much sooner. I have more power and best of all improved fuel consumption, mixed driving MPG is up from 37mpg to 46mpg, better than I could have hoped. I was actually thinking of changing car, but not now! Thank you!

  • Paul from Biloela, Australia with a SsangYong Actyon Sports 200 XDi 141 said:

    Installed the CHIP in my SsangYong Actyon Sports, installation was easy, I felt an instant difference. I now have no turbo lag and a noticeable increase in power, improving acceleration and overtaking performance. I may just trial further increased settings in the future but for now I am impressed!

  • Dadi from Gardabaer, Iceland with a Toyota Land Crusier 4.2 TD 204 said:

    The chip arrived as promised. I have to say that it exceeded my expectations, good instructions and easy to install. Performance is now significantly better, thank you!

  • Matt from Wurtulla, Australia with a Nissan Navara MK1 2.5 ST-R D22 133 (AU Spec) said:

    I have purchased a Chip Express from you and have installed it. It has transformed my Nissan Navara ST-R 2.5 2012 into a vehicle I love to drive. It’s got so much grunt I often search for a taller gear that isn’t there! Cheers Matt.

  • Ian from Scaynes Hill with a Mitsubishi Shogun 2.5 TD Sport 115 said:

    I just wanted to send a bit of feedback regarding the unit I fitted to my Shogun Sport Equippe 2.5 TD. The unit was ordered and delivered very quickly indeed, an absolutely fantastic service! I drive around 400 miles weekly and tow at weekends so I was able to discern the difference immediately and it is really very good. The car revs smoother and higher, there's no need to rev the engine a little bit whilst pulling away now as it feels like the power is instantly available from a standstill. The usual clutch/gear change jerk has totally disappeared, and its just like driving a normal car now. There is definitely a lot more power and torque in every gear with smoother and quieter running. Overall the cars performance has been totally transformed. I can honestly can say I am quite impressed with the unit as well as the service that Chip Express have provided, thanks!

  • Paul from Hillsborough with a VW Amarok 2.0 BiTDI 180 Auto said:

    Just a few words to let you all know at Chip Express that I was delighted with the very quick delivery of the tuning system (less than 24 hours!), fitted in about 1 minute, results are brilliant, seems like a different vehicle! Thank you.

  • Paul from Brisbane, Australia with a Toyota Land Cruiser 4.2 TD 204 said:

    Firstly thank you for your prompt delivery. I installed on the preset settings and the difference is great. The power is there straight away, less lag as my car is an automatic. It’s only the first day but if it keeps performing like this I will be very happy. Thanks again from sunny Brisbane, Australia.

  • Johny from London with a Nissan Qashqai 1.5 dCi 106 said:

    I installed the chip on my 2008 Tekna edition 1.5 dCi, the difference in performance could be felt straight away! The chip was very easy to fit and I am VERY pleased with the transformation, thank you once again!

  • Nigel from Ashford with a Toyota Hilux MK7 3.0 D-4D / Facelift / 07-2011 Onwards / Auto / 171 said:

    I fitted the unit early January and have run it now for 2500 miles (two trips were 500+ miles) the difference in performance is excellent. It basically drives properly as it should now. Recommended to anyone with a new Invincible!

  • John from Boldon with a Mercedes C219 CLS320 CDI 224 said:

    I have had the CHIP Express tuning chip fitted to my Merc CLS 320 CDI since 2009 and find it very good, power is increased for when needed and I achieve around 12% better fuel economy, spot on!

  • Alan from Norfolk, Downham Market with a VW Touarn 2.0 TDI PD 140 said:

    It has now been 5 months and without altering the supplied chip settings we are very very pleased with performance; miles per gallon, acceleration and the smoothness of the vehicle - it lives up to everything your website says. We have found that economy has increased by at least 16mpg solo and when towing the caravan it has increased by approximately 5mpg. We would recommend this product (although the price seemed a little daunting), the rewards far outway the costs and will continue to do so!

  • Brad from Woodford, Australia with a Nissan Navara MK1 3.0 DI 150 (AU Spec) said:

    I received my chip today and I am over the moon. It didn't take anytime at all to get to me. It took me minutes to fit, the hardest part was removing the original plug. The best thing I have bought for my car!

  • David from Cambridge with a Hyundai Santa Fe MK2 2.2 CRDI 197 said:

    After simply fitting my chip to the new generation 2012 Santa Fe automatic the car gave an impressive return in economy, up from 37mpg to 45mpg. Torque is now out of this world, I can’t wait to tow with her. As a company you are one of the best I have dealt with, going that that extra mile to satisfy your customers. I will recommend you to my friends and others, well done CHIP Express!

  • Andrew from Deer Island, New Brunswick, Canada with a Freightlin​er Columbia MBE 4000 12.8 450 said:

    I received power box from you in February and since then have had no problems and it has transformed the performance tremendously. The fitting of it was a bit of a challenge as I had to work outside in sub-zero. I find the engine runs smoother and pulls smoothly from 1000rpm. I can't give you a true picture of fuel economy right now as we have been using winter fuel, (80% kerosene) and I have chunky snow tyres on the drive axles at the moment. However, fuel mileage has been good considering the adverse weather and terrain. Very pleased. With summer low resistance tyres and normal fuel I should see a great improvement. All in the unit is working great and very pleased and would highly recommend this to others.

    We have the system on our Cummins Mercruiser Diesel QSD 2.0 150 and we are happy, especially about the fuel economy on our Revenger 23 RIB. If you want a sponsor I'm happy to put a sticker somewhere on my boat!

  • Adrian from Jondaryan, Australia with a John Deere 9770 STS 9.0 R6 360 said:

    Just to let you know I fitted a CHIP Express to my JD 9770 Combine with excellent results, more power and less fuel (8 to 10 litres/hr) making harvesting a lot easier under difficult conditions. I have had the unit over 12 months now without any problems. The chip is priced very well compared to other brands. Thank you very much!

  • Harvey from Cheltenham with a Massey Ferguson 8690 8.4 R6 AdBlue 370 said:

    Ordered online and got my chip the next morning. It is now fitted it to my Massey Ferguson 8690. I am currently running on a fairly high setting and it runs great, no codes, just pure POWER! A great service, thanks.

  • Mergim from Stockholm, Sweden with a Audi A5 2.0 TDI 143 said:

    Got my chip today and installed it! Works perfectly! I'd rate your service 10/10, super-fast delivery (barely 48 hrs to Sweden), and really easy to install! Sincerely, a really happy customer!

  • Tony from Toowoon Bay, Australia with a Jeep Grand Cherokee MK4 3.0 CRD 240 said:

    I am very happy with the tuner on my WK11 Grand Cherokee CRD 3.0L. I was a bit sceptical at first but after towing my 2.6 ton caravan from Sydney to central QLD I am convinced. The ease with towing is so much easier on the car than standard, I don't have to put my foot down as much going up hill AND get better mileage. Thanks for the great service, help and advice!

  • Kaj from Waterlooville with a Mercedes C200 CDI W204 136 said:

    I received the chip tuning box next day by special delivery. Opened it up and had a close look then took some time to read the instruction manual before fitting. I did not change the settings on the box, just kept them standard. Left the engine on idle for few minutes and checked for any error messages or lights on the dash, there were none. Car was idling as normal and I could feel the engine running smooth. Switched it off and finished the installation. I could not wait to jump in the car and test drive it! Well, first impressions are great; the car felt very different with a lot more power, acceleration is fantastic. I drove a good 20 miles. Felt like I had a lot more power in low gears as well as high gears and I didn’t have to press on the accelerator to much. The 60 mile journey to work this morning felt so much better. I was hardly touching the pedal at 70mph and the trip computer gave a reading of 55mpg compared to 47mpg average. I will be recommending you to my friends.

  • Chris from Rugby with a Mercedes C220 CDI W204 Blue Efficiency 170 said:

    I fitted this little box of tricks and to be honest I am one of the world’s most sceptical when it come to bold claims, also I am no mechanic, in fact the most I ever do is top up the oil, water and tyres. Fitting the unit was so easy even I could do it, instructions so clear you can’t go wrong. My first impressions of what this chip unit is doing is amazing, most of all is the increase in fuel economy, its early days but it looks like a 15% improvement, the power output has also increased by a good margin making the car much more fun to drive.

  • Kevin from Hilbank, Australia with a Land Rover Discovery (2) TD5 138 said:

    Just installed the chip to my Land Rover Discovery 2 TD5. The system was easy to plug-in and the instructions are second to none. Took the Disco out for a run in the Adelaide Hills and what a difference, turbo lag gone, engine noise gone, feels like a different vehicle. Can’t wait to go for a long run with the camper trailer. Very happy with my purchase and would recommend you to anyone.

  • Graham from Narrogin, Australia with a Nissan Navara MK1 3.0 DI 150 (AU Spec) said:

    Received my chip yesterday and fitted it that afternoon, noticed a big difference straight away. Awesome power improvement on hills and pulling away in a higher gear at lower speeds, but was even more impressed with the power increase it has on the highway. My confidence with this slug has grown significantly and my Navara is now a force to be reckoned with! Money well spent; glad I found your website!

  • Graham from Melton Mowbray with a Skoda Octavia MK2 1.9 TDI 105 said:

    Chip arrived next day as promised, and set to work on it that same afternoon. Straight away the car felt smoother and could use higher gears sooner. Tried it in 5th gear at 40 mph and it pulled away quickly. Very pleased so far!

  • Robert from Stoke on Trent with a Toyota Hilux MK7 3.0 D-4D / Facelift / 07-2011 Onwards / Auto / 171 said:

    Had your chip for 12 weeks now and tried all different tests (on and off), I do the same 250 mile trip most weeks and lots of urban driving. I am a pessimist at heart but can’t fault your chip. My 3.0 D-4D Invincible automatic is a different car with the chip fitted, performance and economy is so much improved, for anyone owning a Hilux this is a must as it transforms the car!

  • Steven from Stoke-on-Trent with a Land Rover Range Rover (3) 4.4 TDV8 313 said:

    I would like to pass on my sincere thanks to CHIP Express for a first class product and service. I am very pleased with the improvement in performance and economy. Many thanks.

  • Tim from Morthoe with a BMW F10 520d 184 said:

    On Saturday I received my upgraded chip - great customer service! Originally fitted to my BMW E60 530d performance and economy easily matched what was quoted and I was more than pleased. Having just fitted the reprogrammed chip to my new 520d I just wanted to inform you that once again performance is very impressive. Fitting was also very easy thanks to the clear instructions. I will continue to recommend you, a fantastic product from a fantastic company!

  • Grant from Flat Bush, New Zealand with a Audi Q7 3.0 TDI 245 said:

    I installed the chip in my 2012 Q7. Amazing difference in both power and smoothness. I have had it in the car for about two months and recently took it out to get serviced, really noticed the difference when driving to and from the Audi dealer. Would definitely recommend anyone with a diesel buys one!

  • Timothy from Teignmouth with a Fiat Ducato 2.3 130 Multijet 130 said:

    This is my second Ducato based motorhome to be fitted with a CHIP Express system. On both occasions the chip was simple to fit (idiot proof) and made a remarkable difference. I am very satisfied and would recommend this company to anyone for an excellent service!

  • Anthony from Wolverhampton with a Fiat 500 1.3 Multijet 75 said:

    Many thanks for your fantastic service upgrading my CHIP Express module. The Fiat now drives much better with more low speed torque and throttle response, also better MPG. This is my second CHIP Express tuning module and for the last 30 months I have been saving at least 10% on fuel with excellent performance in my Volvo 2.4 D5. I have no hesitation in recommending your product as it gives great satisfaction and will pay for itself with the fuel saved, thanks again.

  • Peter from Taunton with a Nissan X-Trail 2.2 dCi 136 said:

    I was recommended by a relative to try chipping my 2004 X-Trail 2.2 dCi. Low down torque was not ideal for towing my caravan and towing MPG was 25. Although sceptical of chips I thought I'd give it a try. The chip was quickly delivered and very easy to fit. Caravan towing was easier because the low down torque improved dramatically. The engine was also quieter and the MPG went up to 30 when towing. There were similar improvements when driving solo. I am no longer a sceptic - the chip has done what it said it would. I have now changed to a Freelander, and had the old chip modified for the Freelander. Service was again excellent!

  • Craig from Milton Keynes with a Vauxhall Astra J 2.0 CDTI 165 said:

    Ordered Wednesday received Thursday, a great service. It was a doddle to fit on my Astra and its running very well with just that kick of speed on hand should you need it. I am finding myself going out in my car for drives, not because I have to but because I want to!

  • Nutthawut from Bangkok, Thailand with a Toyota Land Cruiser 4.5 D-4D V8 286 said:

    There is a BIG increase in power. Economy has improved by 2km/litre on a long journey and up 1km/litre within the city. I am also using your chips on two other vehicles, a Porsche Cayenne II 245 and BMW F10 520d 184, again superb results! Well done!

  • Robert from Northolt with a Hyundai i40 1.7 CRDi 136 said:

    As per my quick phone call earlier today, once again thank you for the tuning chip, wow, what a difference to the car, it has come alive! Long may your business flourish such a superb product, I will be recommending to my friends.

  • John from Chilham with a Isuzu Rodeo / D-Max 2.5 Twin Turbo Euro 5 163 said:

    Some feedback for you and other Isuzu drivers: I would just like to let you know that I will not be returning this little box of tricks! It has worked an absolute miracle on my new Isuzu, performance is much better but more importantly my economy has gone from an average of 24mpg to 30mpg, slightly more on a long run! If you are reading this and have the new 2.5 litre engine don't hesitate, you need this chip!

  • James from St. Neots with a Volvo S60 2.0 D3 163 said:

    I just wanted to say I have fitted my tuning chip and it now goes like a rocket... it’s got a lot more low down grunt and mid range is superb. Fuel economy was up to 48mpg which is great and much better than before. Thanks again for putting a big smile on my face... a great product!

  • George from Cupar with a Mc Cormick MTX 165 6.7 R6 said:

    I would like to thank you for the chip and the help with it. Lower end torque is much improved, tractor is also now holding a lot more on hills with a load and fuel economy is better on PTO work too, once again thanks!

  • Shaun from Thetford with a Vauxhall Astra H 1.9 CDTI 150 said:

    Astounded, simply astounded! A great car utterly transformed into a thoroughbred with blistering performance. I'm finding myself looking for excuses to use the car more and more, it really is that much more fun to drive. The fact that no tools are required for fitting was a real bonus and economy is now much better too, I'll certainly be recommending this plug-in chip to friends!

  • Glen from Kirkcaldy with a Nissan Navara MK2 2.5 dCi 190 said:

    I am exceptionally pleased with your service, swift delivery and clear fitting instructions. Your chip tune up has given my pickup a well needed boost, not only is the engine running much smoother the increased power band means the gearing is much better suited, especially when towing!

  • James from Annery with a BMW E91 330d 231 said:

    Great product! Fitted first chip to my BMW 320d made it so better to drive no with no flat spots plus better on fuel by about 5mpg. Now fitted second chip to my BMW 330d which pulls like a train which so much more torque, very happy with service, a top company!

  • Calum from Fraserburgh with a Audi A4 MK3 2.0 TDI PD 140 said:

    Ordered the unit from yourselves at 2.30 pm on the Thursday, unit arrived first post on Friday and fitted before lunch time. So easy! Already feel the difference in performance and achieved 56mpg at a steady 75mph with cruise control on. Have left standard settings on. Very happy!!

  • Nick from Penrith with a BMW F10 520d 190 said:

    I have the chip installed and racked up about 1,000 miles. The difference in torque and mid-range acceleration is palpable and very welcome in such a big car. I don’t monitor fuel consumption particularly closely however I certainly haven’t noticed any degradation in that respect despite my heavier right foot whilst enjoying the extra performance.

  • Ian from Burton Upon Trent with a Vauxhall Vivaro 1.6 CDTi Biturbo 140 said:

    My new 2015 Vivaro is running great, the throttle response is improved, RPM's now climb faster and fuel consumption has been reduced. So all in all a happy customer and many thanks to yourselves!

  • Cris from Lymington with a Toyota Land Cruiser 4.2 TD 204 said:

    I cannot believe that I got 31mpg in normal driving conditions. That is a 10mpg difference without a trailer. With a heavy trailer I got 19.8mpg via the onboard computer - that's improved from 15mpg before. I'm looking forward to verifying this with full tank to empty to double check, but power increase on standard setting is impressive, torque is very much improved!

  • Mark from with a Audi A8 MK2 3.0 TDI 233PS said:

    I fitted the tuning box to my Audi A8 3.0 TDI very easily. The car runs so smoothly and has all the power one would need and yet gives an easy 48mpg on a run. I am getting the box reprogrammed for my new car. I have bought my new car with CHIP Express tuning in mind. A great company that has to be backed by enthusiasts. If only they could see our smiles!! Thanks guys.

  • Clive from Pulborough with a Audi A5 2.0 TDI 177 said:

    Staggered. Sceptical to start with. 10 minute installation and performance improvement. Perhaps not quite as significant as I expected but nonetheless mid range torque so much better. Engine and gear changes smoother. MPG FANTASTIC. Prior to tuning 21,452 miles at an average 42.8 mpg. Since chipped 1,017 miles at 52.3mpg. Same journeys as usual. I do 15k mile p.a. the chip will pay for itself in less than a year. Tap tap boom!

  • Sinclair from Richmond, USA with a Land Rover Range Rover Sport (2) 3.0 Td6 258 said:

    I received the CHIP Express for my 2016 L494 Td6 US version. The installation is very easy. Just need to pay extra attention to make sure the pugs is correctly orientated and locked in position. I initially used the by-passed plug supplied with the package to do a test before plugging in the Chip Express. Then, I plugged the Chip Express with it default setting. The different is very noticeable during acceleration! The tachometer just raced to 4k rpm so fast that I wished it could rev pass that before changing gear! The difference for 0-60 time is about 0.4 - 0.5secs (averaged) after 3 runs. The most important one is the ability to overtake and merging can be done a lot faster now. Now it feels comparable to my Cayenne S (957) performance with less fuel consumption! I recommend this product to any Td6 (US version) owner that is looking for additional performance to make it to almost equal the SDV6's performance.

  • Robert from Newark with a Land Rover Discovery (2) TD5 138 said:

    I recently purchased one of your chips for my Discovery TD5 and after installing it I was amazed with the extra power gain which will help when towing my caravan!

  • Phillip from Hindringham with a Renault Master MK3 2.3 dCi Euro 5 125 said:

    Regarding my Renault Master Van MM33 dCi - I have recently purchased one of these units and am very satisfied with the performance improvement. Thank you.

  • Michael from Aberdeen with a Toyota Hilux MK6 2.5 D-4D 144 said:

    Just a quick note to let you know how very pleased I am with the chip for my 2012 Hilux. Its a different truck, well worth the money, would recommend everyone to try it out. One very satisfied customer!

  • David from Manukau, New Zealand with a Jaguar XF MK1 2.7D 207 said:

    Fitted the chip in minutes and noticed the improvement in performance immediately, much smoother changes and a better power band. Have just check my fuel usage and now am getting an average on highway of 6.7L/Km, has been as low as 6.2L, the best I got before was 7.8L. Thanks, great product and delivery.

  • Chas from Bendigo, Australia with a Land Rover Discovery (2) TD5 138 said:

    The chip unit turned up today, the great news is, I installed it, the led lit up, so I went for a run, struth! I could tell the difference straight away, once again, many thanks, bloody oath mate, the car is going gangbusters, at the moment I feel there is no need to alter the settings, it will be two weeks before we hook the caravan up, I can’t wait to see how things go!

  • Helen and Graham from Ballinderry with a Mitsubishi Shogun 3.2 DI-D 160 said:

    I am very well pleased with the performance of my Shogun since Graham fitted the chip. It is a real pleasure to drive now with more torque in lower gears. I will be highly recommending this product.

  • Richard from Hull with a Hyundai Tucson MK1 2.0 CRTD 140 said:

    Fitted the chip today, WOW, what a difference! Pulling power and acceleration are unbelievable, so smooth. Transformed the car from good to excellent. Keep up the good work.

  • Gordon from Loughborough with a VW Scirocco 2.0 TDI 140 said:

    In 2009 I bought a tuning kit for my Scirocco 2.0 TDI GT with good results for the 2 years or so I had the car. The system is was easy to fit and gave improved drivability, power and economy. I have just bought an Audi A5 3.0 TDI Quattro Auto (240PS) and have upgraded the same chip for use on this vehicle. I wouldn't hesitate to recommend CHIP Express!

  • Brendan from Hertfordshire with a Audi Q5 3.0 TDI 240 said:

    I first researched such chips when Audi kindly announced the soon to be released SQ5, as they were getting so much more BHP out of the same engine by way of a twin turbo. I looked at various companies, but I am so happy I came across CHIP Express as it has completely transformed my car, both in terms of power and economy. I actually wasn’t that bothered about the economy and was sceptical that (on standard setting, as I have left it) I would increase from 240bhp to 280bhp and also see an improvement in economy, but as soon as the chip was fitted (which took 5 minutes) the car was noticeably more powerful! It also has much smoother and quieter gear changes, especially at slow speeds, which seems crazy in a new car? In “sport” the performance seems monstrous for an SUV, whilst still being smoother and quieter! Economy – now the best bit is the bit I was least bothered about! My economy on daily commutes (short and medium runs) has seen the average go from 27mpg to 33mpg. That means instead of 540 miles from a full tank I’m up to 660 miles! Quite simply this is the best money I have ever spend on any gadget for any car. Even my wife loves it and she fell out with me when I placed my order. I would never have another diesel car without fitting one of these chips and cannot recommend then highly enough.

  • Keith from Eastleigh with a VW Tiguan MK1 2.0 TDI 140 said:

    Have just fitted my CHIP Express and all I can say is WOW! I can not believe how lively my car is now, it has made such a difference. Money WELL spent, thanks!

  • Glenn from Brisbane, Australia with a Toyota Hilux MK7 3.0 D-4D Auto 171 said:

    Just thought I would let you know how happy I am very happy with the unit I purchased. I have had it fitted to my 2014 Toyota Hilux / Vigo Champ 3lt Auto for just on a year, I fitted it at 10,000 klms. I only remove it when I go for the scheduled services at the local Toyota dealer, just in case they disprove of it whilst the vehicle is under warranty. As soon as the service is complete I refit it straight away as the difference in driveability, i.e. power, auto gear shifts and smoothness is so noticeable. I have also achieved about a 5%+ fuel saving. Before I ordered the unit from you I was hoping I was not wasting my money, but the unit has exceeded my expectations and lived up to all your claims. I have no hesitation in recommending your diesel chip units to anyone who is interested. Cheers Glenn (Aussie Expat Thailand).

  • Richard from Swindon with a Mercedes A-Class W176 A180 CDI Auto 109 said:

    Well done CHIP Express. This is my third unit and am more than satisfied with the results. My usual journey covers 60 miles and the car returns about 57 mpg, after fitting the chip it achieved 67 mpg. That together with much smoother acceleration had me wondering if it was the same car! I now look forward to my next trip, most impressive and many thanks.

  • Matthias from Switzerland with a Land Rover Range Rover 3.0 (3) SDV6 256 said:

    I am very satisfied with your kit, it is easy to set up and works really well, I felt a big increase in power. Consumption is also now lower than before. A very good product with great engine specific instructions and excellent e-mail support. I am glad I found you on the net!

  • Ashley from Dumfries with a Mercedes C220 CDI W204 170 said:

    I can't tell you just how very thrilled I am with your product which I fitted with no difficulty whatsoever, a few days ago. The car has been totally transformed! All the claims made in your advertising have been met, and, in my mind, superseded. Additionally, to come across a company with such high standards of customer service, is refreshing to say the least. Well done for producing a product that has such an ability to greatly increase our enjoyment of our vehicles performance, with the added benefit of improved fuel economy as well. I shall definitely be recommending CHIP Express to all my friends.

  • Peter from Worthing with a Nissan Qashqai 2.0 dCi 150 said:

    The extra performance was instantly noticeable. Having now returned from our French holiday and 1600 miles later, and considering we were fully loaded and seriously motoring; the overall average fuel consumption rose from 34.9mpg to exactly 43mpg. Thank you again for all your help and attention, your chips are regularly being spoken about in high regard.

  • Rob from Watford with a Mazda 6 MK3 2.2 SKYACTIV-D 150 said:

    Just had my chip fitted to my 2015 Mazda 6 150 Sport and it has exceeded well all expectations. It has been fitted on the factory supplied setting and provides excellent acceleration and torque. I will settle for factory setting for now. Impressed!

  • Desmond from Camberwell, Australia with a Audi Q3 2.0 TDI DSG 140 said:

    A great product, I am very happy with it! Since fitting the Q3 drives much smoother and the DSG transmission is better mated to the engine. It is still very economical and the downshifts are now much faster and more precise - instead of a the big jerk on the original tune. Torque has increased and there is more pulling power when taking off from a halt which helped me a lot in traffic. I was going to upgrade to the 170PS / 130kw model but don't need to anymore. I used to have to put it in SPORT mode to get it to go but now the normal mode is more than enough. I am very happy with optimum tune provided.

  • Gordon from Tipton with a VW Golf MK7 2.0 TDI 150 said:

    Just to let you know that I've been running the chip for 4000 miles now and am impressed with the results. I noticed the difference immediately with low end power and have seen huge gains on motorway MPG. Put the car in sport mode and its unbelievably quick and no smoke (as I have found with cheaper chips). I would thoroughly recommend CHIP Express to anyone, with the savings I'm making with fuel the chip will have paid its self off in no time!

  • Nick from Croydon with a BMW X3 18d 143 said:

    Only just got around to commending you on the supplied chip for my BMW x3 143PS. Interesting that BMW have upped the power on the facelifted X3 to 150PS but the chipped version you have supplied is more powerful and responsive - it just can't wait to get into upper gears! MPG average is already creeping up. I also find the engine quieter, more driveable and 'fluid' in all road conditions - looking for an excuse for a long run! Well done.

  • Kieran from Liversedge with a Porsche Cayenne 3.0 Diesel II 262 said:

    I fitted my new chip this weekend to my 2016 Porsche Cayenne 3.0 Diesel. This was very easy to fit and I don't have any issues with idling etc. The increase in power is clearly visible and the vehicle now drives like a Porsche should!

  • Kieran from Adelaide, Australia with a Land Rover Range Rover (3) 3.6 TDV8 272 said:

    I would like to give you some feedback on the CHIP Express I purchased off you about 2.5 years ago for my Range Rover TDV8, 3.6L. The chip came pre-set on the middle setting and after installation which was very easy, I settled in with it installed and basically forgot about it being there until the other day when I decided to make a couple of adjustments. The difference in power was huge, no spluttering or lights coming on the dash just pure raw power coming out of the motor. Thanks!

  • Stuart from Sydney, Australia with a Land Rover Discovery (2) TD5 138 said:

    I ordered a chip for my TD5 after some research. CHIP Express answered all my questions prior to purchase very quickly and efficiently. A nice customer service experience. Although a little nervous the nicely detailed instructions guided me through the install painlessly. What a pleasant surprise, my Discovery TD5 now purrs up hills and overtakes with ease with just the touch of the accelerator. It’s nice when promises are delivered and customer service is above excellent!

  • David from Basingstoke with a Audi Q5 3.0 TDI 240 said:

    I ordered a chip for my Audi Q5. I was immediately impresses by the packaging which reminded me of the same quality and attention that Apple employ for products such as their iPhone's. The instructions which included photos of my specific engine made fitting an absolute doddle. And the results? The engine feels much more eager and responsive when you put your foot down as the extra horses and increased torque kick in. It works perfectly with my 7 speed DSG gearbox which is clever enough to change up or down dependant on engine load, and now it seems to select a higher gear at lower speeds than before, less throttle is needed for normal driving which had my average economy edging toward 40mpg (normally 32mpg) for an urban journey of less than 12 miles. Looking forwards to seeing if I can better my 43mpg on a run from Hampshire to Cornwall in a few weeks. Think I'll leave the chip on the supplied setting as so far it's giving me everything I'd hoped for.

  • Steve from Royal Palm Beach, USA with a Dodge Ram 1500 3.0 EcoDiesel V6 243 said:

    I'm extremely impressed with my CHIP Express system. More power, better mpg and absolutely outstanding customer service, the best I have ever encountered.

  • Tat from Bradford with a Audi A5 3.0 TDI 240 said:

    Due to a change in car I sent my CHIP Express box back for reprogramming. I sent on a Thursday and had it back Saturday morning, now that's a fast turnaround! I originally had the box installed on my Audi A3 2.0 TDI, primarily for the additional performance which it delivered by the bucket load. This time I wanted the chip for the extra economy, which again it has delivered on. I cannot recommend this product enough, it does as promises with great service to top it off. What's not to like?! Many thanks.

  • Mike from Fairfield, United States with a Mercedes ML350 CDI BlueTEC 211 said:

    Just wanted to let you know the chip arrived for my 2010 Mercedes ML350 diesel a couple of weeks ago. I installed it last week, and the results are exceptional! In particular, I had occasion to make a long highway drive two weeks ago (prior to the chip) I got 26.8 mpg on the trip of 900 miles, mostly on the cruise control at 75 mph. I installed the chip last week, and made the exact same drive, same highway, same weather, except at mostly 80 mph on the cruise control. I averaged 31.05 mpg on the second trip – an increase of over four miles per gallon, at a higher speed. I have also experienced a substantial improvement in acceleration, though I don’t have a baseline for comparison. At 73 years old, I don’t do much street racing any more… but, there was this guy with a Mitsubishi Eclipse the other day… Anyway, I just wanted to let you know the chip really did what it is supposed to do. Extremely impressive.

  • Vasileios from Thessaloniki, Greece with a Mini 2nd Gen. 2.0 SD 143 said:

    I am writing to live a feedback about my chip for my Mini 2.0 SD Auto. After installation the first thing that I did was to measure the results (I was sceptical). The result was very impressive, everything I was told to expect is true! After 6 months of use I can confirm the engine runs smoothly and the fuel consumption with my heavy foot is better by about 15%. I strongly recommend CHIP express, it is worth every penny!

  • Roger from Cippenham with a Audi Q5 2.0 TDI 170 said:

    Being a service provider myself I just wanted to say how pleased I am with the chip. My god, what a difference! Much more responsive with a much fatter torque curve. Even though I ordered late in the day the kit was here the next day. It was a 5 minute job to fit. With regard to the price, in 2004 I spent £3600 to have a John Cooper Works kit fitted to my Cooper S Mini for the same increase in power! A great bit of kit CHIP Express - well done!

  • John from Epsom with a BMW E53 X5 3.0d 218 said:

    Fantastic performance from this small box. Minutes to fit. Transforms the driving. Engine runs smoother. Acceleration amazing. Looks like around 30+ mpg town driving. Wish I had done it sooner. Excellent service and back up. Would recommend to all.

  • Raj from West Drayton with a BMW 5 Series F10 535d 313 said:

    I have just sold my BMW 535d which was previously fitted with your chip box. After 2 years of fault free driving, I have nothing by praise for CHIP Express. I never got a single fault code, nor did I get any excessive smoke, just a noticeable power increase that made the car more enjoyable to drive!

  • Tony from Sittingbourne with a Nissan Navara MK2 2.5 dCi 190 said:

    Just fitted the CHIP Express I ordered from your company. My Navara Tekna 190 D40 feels like the figures you quote on your website. No smoke, lots of pick up, well worth the money! Thank you so much.

  • Rod from Los Angeles, USA with a BMW X5 E70 xDrive 35d 269 said:

    Greeting from Los Angeles, CA USA. I purchased a Chip for my 2011 BMW 335d and was so happy I purchased another for my 2012 BMW X5 35d. These chips are super, they deliver exactly as advertised, delivering improved throttle response, increased performance as well as improved fuel economy. I was getting around 20 mpg with in town driving and now am getting just shy of 23. Get one, you will not be disappointed!

  • John from Grimsby with a Diesel Tuning Chip for Kia Ceed 1.6 CRDI 126 said:

    I have now fitted my orignal chip to my third Kia Cee'd 2014 126PS SW, before this I had a Kia Cee'd 1.6 90PS and then a Cee'd SW 115PS. Before refitting I ran the car towing a caravan and town and distance runs for about two months. I have now fitted the chip and once again the car is transformed. When towing I used to have to gear change twice on small inclines, now I dont have to change gear at all, the car just pulls away on hills. The fuel average is considerably more, the engine runs smoother and the performance is like having a 2ltr. Thanks to your staff for sorting me out!

  • David from Olney with a Skoda Octavia MK3 2.0 TDI 184 said:

    Chip arrived this morning and within 30 minutes car was transformed. Really pleased with the ease of installation and the outcome. Thanks a lot to you all.

  • Mark from Godalming with a BMW F30 320d 184 said:

    Had a CHIP Express chip in my BMW E90 318d 143PS for 18 months and been absolutely delighted with it. I returned the chip for an upgrade when I changed my car to a BMW F30 320D xDrive M Sport. The upgrade was done in super quick time and the installation quick and painless as usual. After about 2000 miles of driving in all conditions I'm pleased to say that the chip works even better than before! My MPG has gone up by about 12-15% and I can push about 600 miles out of a tank (up from just over 500 before the upgrade) and the difference in the acceleration in all gears (including Sport mode) is fantastic. It's a completely different car, which is now more efficient and more powerful - feeling basically like the next model up in the range! Many thanks for such a fantastic serivice and product!

  • Richard from Baxter, Australia with a VW Transporte​r T5 2.0 BiTDI 180 said:

    We have purchased several units for our diesel VW cars and vans and have been seriously impressed with the fuel saving and added power. I recently installed a unit in the T5 BiTDI in 2013. We only used half a tank of fuel to achieve 550 km's, before the same would have taken 3/4 of the tank. This particular trip included overtaking on a long country drive through the mountains to go skiing. I would recommend these units to anyone interested in improving economy and performance.

  • Andy from Ferryhill with a Volvo XC70 2.4 D5 215 said:

    Just fitted the CHIP Express tuning box (in less than 5 minutes) to my Volvo XC70 and the difference was what I expected - BRILLIANT, this is the 3rd car that I have used CHIP Express with and will continue to use on all future cars. We all spend thousands on our cars and an additional few pounds changes a normal car into a car that gives increased pleasure from both performance and MPG, money well spent. Thanks.

  • Marrel from Indonesia with a Nissan NP300 2.5 dCi 133 said:

    Bought myself and three friends a CHIP Express. The other cars bought for were for 2x Ford Ranger 2.2 150's and a Nissan Navara 2.5 D40 174. The chips all work perfectly and have instant changes towards the torque range which is very handy because we do a lot of off roading. No warning lights on any of the vehicles, we are all very satisfied with the product and great customer service!

  • Neil from Berwick-upon-Tweed with a Kia Optima 1.7 CRDi 136 said:

    I have had the chip fitted for a month and now done approx. 3000 miles having just returned from a trip to Cornwall from Scotland. To say I am impressed would be an understatement. The car itself is quite rare on the UK roads and the acceleration has turned a few BMW and Audi drivers heads, a few asking what engine is under the bonnet? On a long run the fuel consumption was in the high 50s to low 60s - impressive. I have been driving for over 60 years and driven many different vehicles however to improve the performance of a standard engine by simply fitting a little box is outstanding. My son-in-law is a Kia Tech and said after taking it for a test run that if they fitted them in the factory they would sell many more cars. Recommended: YES!

  • Steve from Morcambe with a Renault Laguna II 2.0 dCi 150 said:

    Just a big thanks for your promptness. Two days from sending my old Citroen C5 II 2.0 HDI 135 chip to receiving it back fully programmed for my new Renault Laguna II 2.0 dCi 150. A brilliant service, the tuning chip works just as claimed. As per the Citroen the Renault is now smoother with much less turbo lag and much more torque. Many thanks!

  • Stephen from Grimsby with a VW Golf MK7 2.0 TDI DSG 184 said:

    I sent my chip back to get an upgrade from a MK6 Golf GT to a Golf MK7 GTD DSG, the turn round was only 2 days from posting. The DSG auto box is so much smoother and the fuel consumption is also much better, for example set cruise at outside lane motorway speeds today and got a return of 58.9 mpg. I have had this chip now for 6 years on different Golfs and it has never let me down!

  • Scott from Meriden, USA with a BMW 3 Series F30 328d US Spec 183 said:

    I just wanted to let you know how impressed I am with my chip tune. Installation was as easy as it gets and BAMMM, huge difference. Its like a whole new car. I actually bought Dyno-Scan from Auterra which runs on my Galaxy S4 through Bluetooth connected to the OBD II port to measure the HP/TQ and the results were 228BHP and 366 LB-Ft TQ. No one should hesitate to buy this tune for their cars, they won't regret it.

  • Simon from Sandbach with a Alfa Romeo Giulietta 2.0 JTDM-2 TCT Auto 175 said:

    In mid 2014 I hesitated in buying a unit for my car as none of the providers at the time were showing a unit for a Giulietta with the specific engine and transmission I had on order. At the time that was the latest version just released. I came across CHIP Express and found they did offer a unit. I took the plunge and fitted it after putting as few hundred miles on the clock. The difference in power and flexibility was noticeable immediately. Mid range acceleration in particular was much faster and fuel economy improved too. I am delighted with the CHIP Express tuning box. The car originally produced about 175PS and certainly now feels more like 210PS. If you want to transform your car buy one!

  • Geoffrey from Warnbro, Australia with a Kia Sorento MK2 2.2 CRDI 197 said:

    Just wanted to say that I am truly impressed. I was sceptical about how this would help my Sorrento. But straight away noticed more power when taking off and much smoother gear changes on the auto. It has also smoothed out my downshifts when slowing down (the main reason I wanted it). The Kia was a little sluggish and the 1st gear to 2nd gear change was a little harsh, now this has made the car just awesome. Have kept it on standard settings and am very happy with the gear change improvement and power improvement. Thanks guys!

  • Brad from Melbourne, Australia with a Nissan Patrol 3.0L VP 160 said:

    Brilliant, better than expected, ZD30 flat spots no longer exist and EGT's are safe! Arrived in Austrailia in nine days so now can't wait to pack the van and kids and maybe the wife to hit the sand dunes for Xmas again! Cheers guy's, I will recommend you!

  • Glenn from Narberth with a Audi A3 MK3 2.0 TDI 150 said:

    Many thanks for your prompt delivery. Fitting instructions were easy to follow with excellent engine layout photographs, the chip was fitted in minutes without any complications. My A3 Cabriolet really needed an increase in power for overtaking and the first initial response on driving the vehicle was absolutely awesome, the low and mid range torque increase on the standard setting has made a huge difference to the already nippy performance. I have now adjusted the chip to maximum and this has well exceeded my expectations, overtaking is rapid, engine is smooth with no lag and I'm still getting 55-60mpg. I would thoroughly recommend this product.

  • Michael from Las Vegas with a VW Golf MK6 2.0 TDI US Spec 140 said:

    Absolutely loved the performance upgrade on my MK6 VW Golf. A noticeable increase in power and about an overall increase in mpg of 10% highway and city. I have already upgraded the old unit for a new one for the 2015 MK7 VW Golf I have on order. The only thing better than the Chip Express unit is the Chip Express customer service!

  • James from Gloucester with a Vauxhall Astra H 1.9 CDTI 150 said:

    I can't recommend this system highly enough! I have had a CHIP Express system fitted to my Saab 9-3 1.9 TID 150 for a few years and now I've bought another chip for my Astra Twin Top. The 9-3 and Astra share the same engine so I could of just swapped over the box from one car to the other - but because the CHIP Express has transformed the driving ability and economy of the Saab so much I would not want either car without it. Incidentally when I bought the Astra the previous owner gave me a tuning box that he had fitted. Unfortunately it was nowhere near as good as yours and when fitted after a few days it put the car into limp home mode causing a light to pop up on the dash. Anyway as expected and once again the CHIP Express box has worked wonders, effortless power, no flat spots and far better economy. It's changed the Astra convertible from not just being fun in the sun but fun all year round!

  • Ben from Howell, USA with a Audi Q7 3.0 TDI Clean Diesel / US Spec / 2013 Onwards / 240 said:

    I'd like to let you know that I'm very pleased with your product. I enjoy the increased fuel economy (31.5 mpg) and the never ending pulling power our 2014 Q7 TDI has with the help of your tuner!

  • Bruce from Broxburn with a Kia Sportage MK2 2.0 CRDI 140 said:

    I fitted your system to my 2006 Sportage, it has transformed the car. Incredibly while towing a caravan I managed to return 5mpg more then my brothers slightly newer but identical Sportage!

  • Olli from Surrey, Canada with a BMW 3 Series F30 328d US Spec 183 said:

    I have installed the Chip Express, it is terrific! Installed it in 5 minutes... performance is great... the engine feels and sounds totally unstressed... best increase in performance for the money, period! You can put me down as a very satisfied customer... p.s. if you want to add me to the reviews, feel free!

  • Brian from Crawley Down with a Mazda 6 MK2 2.2D 180 said:

    I purchased this in Sept '14 but have waited a few months before writing a review. It's simply brilliant, reasons? (1) Improved fuel consumption under normal driving conditions (2) Noticable improved flexibilty in gears especially at slower speeds (3) Smoother engine (4) Big improvement in performance which, when used doesn't use a huge amount of extra fuel (5) Much improved torque. I got a professional to fit mine (he knew Chip Express products well) and we initially used the default mid-way setting. After trials we settled on the default setting but fine tuned it to maximum. This gave a big improvement on the edge of Traction Control kicking in so there's no stress, just a big overall improvement. Our 2011 Mazda 6 Sport (180) was quite quick anyway but this has made all the difference - more fun, even easier to drive and better fuel consumption. The car feels better for it. I therefore have no hesitation in recommeding it. I only wish I'd bought it sooner. Only one tiny downside is it does confuse the average MPG indicator but having carefully checked it, it shows 4 MPG less than is true. For example - shows 46 but is actually 50 - no complaints! Just buy one!

  • Mike from Andover with a VW Golf MK7 2.0 TDI 184 said:

    I have just bought one of your chips for my Golf GTD, 2013. Having fitted it within minutes I am astounded at the difference it has made to an already quick car. There are no flat spot at all in any gear and it will now spin the wheels in second gear if you floor it!

  • Neil from Milnathort with a Audi A7 MK1 3.0 TDI 204 said:

    My chip on the Audi A7 was perfect in every way, instant power and on average a minimum of an additional 6 mpg. Never had a problem from easy fitting to recent removal. I recently sold my Audi A7 and bought a Volkswagen Touareg 3.0 TDI. As I wanted to chip my VW I asked for advice as to whether I could swap this onto my new car, fully expecting that the chip may need reprogramming at a price, not so! CHIP Express confirmed that the chip will plug and play without any need for adjustments as both the Audi and Volkswagen use the same engine. I cannot recommend the product and company highly enough. Don't go for cheap and nasty. Go for trusted service, absolute honesty and reliability from the guys who know!

  • John from Melbourne, Australia with a Toyota Land Cruiser 4.2 TD 204 said:

    I was told by a Toyota mechanic that your perfomance chips were best, my old chip from another supplier gave me nothing but trouble. Well just to let you know that your simple fit chip has indeed made a a vast improvement, sensational performance with better fuel economy! I have recommended you to my friends who since trying my car will be purchasing from you soon!

  • Paul from Stockport with a Ford Ranger MK5 2.2 TDCi 150 said:

    The chip came on time as promised and is now fitted on to my 2.2 Ranger Limited 2013 model. It certainly now runs a lot smoother and less gear changing is required. It now seems to cruise along in higher gears with no labouring from the engine.

  • Nils from Tallinn, Estonia with a VW T5 2.0 BiTDI 180 said:

    Your tuning box has turned my VW Multivan (T5) 2.0 BiTDI DSG into rocket! It also saves a minimum of 10% on fuel, a much better option then remapping, thank you!

  • Alan from with a Citroen C5 II 2.2 HDI 204 said:

    If you are looking for a chip for your car, then look no further. I originally had a chip on my Citroen C5 I 2.2 170PS and was very pleased with the results. I have installed my re-programmed chip with equally impressive results. There feels to be a big increase in power output with a much smoother delivery throughout the rev range and a bonus of a 5 mpg improvement despite using the extra power.

  • Martin from Rotherham with a Toyota Hilux MK7 3.0 D-4D / Facelift / 07-2011 Onwards / Auto / 171 said:

    My Hilux (bought second-hand) came fitted with the CHIP Express which I removed... temporarily! I can honestly say if i had test drove my Hilux when purchasing without the chip i would not have purchased it, it is totally underpowered, very noisy and grough. CHIP Express is a must have!

  • Vince from Portsmouth with a Audi A3 MK3 2.0 TDI 150 said:

    Many thanks for your speedy delivery. True to your word, I ordered it yesterday and it arrived this morning. Just took the car out on standard setting as supplied and it was impressive from low revs. I've fine tuned it up one position and OMG it's like driving a different car! Am I glad I bought it? From first impressions, OH YES!! Thank you.

  • Nick from Southampton with a Skoda Roomster 1.9 TDI 105 said:

    I've been using a tuning box on my 1.9 Rooster tdi for 3 years and it's been excellent. It's now done 120,000 miles, at the last MOT the smoke test was 0.43, a good pass. Economy is generally 50-55 mpg measured at refuelling, acceleration at motorway speeds is outstanding!

  • Andy from Norwich with a Mercedes E250 W212 CDI Blue Effieicency 204 said:

    Many thanks for your excellent and prompt service. Had bought a chip for my Vito 120 V6 which I found made a great family van into a fantastic powerful autobahn cruiser. Fuel returns were up by 4 to 5 mpg but with better proformance. Now had chip altered by yourselves to fit onto my E250 cabriolet. Very easy to install. Fuel returns about 7 mpg more after after fitting with an increase in power and pulling in gear rather than changing down. Will not hesitate to have chip altered for next car. A very happy client!

  • Vassilis from Peristeri, Greece with a BMW 3 Series F30 316d 116 said:

    I purchased chip tune 6 months ago. The difference was obvious. It does what it says. I tried the same car without CHIP Express. I cannot drive without it!

  • David from Invergordon with a Mitsubishi ASX 1.8 Di-D 116 said:

    When I bought a Mitsubushi ASX I fitted the chip within days of purchasing the car as I had previously fitted one to a Suzuki Grand Vitara and it had provided excellent results. However I was not able to compare the before and after performance on the ASX as prior to fitting the chip I had only driven a few miles in the car. Recently I removed the chip due to a warranty problem with the air conditioning and I have now been driving the unchipped ASX for about a week. The loss of torque is immediately noticeable. I am having to make frequent gear changes in order to overtake whereas with the chip fitted the car pulled effortlessly in any gear once above 40mph or so. In normal driving I am now constantly changing down when coming out of bends, going up hills or pulling away from junctions. As soon as my car has been repaired I will be refitting the chip. Thank you for an excellent product.

  • Richard from Tavistock with a VW Golf MK7 2.0 TDI 184 said:

    What a transformation! Vastly improves the fun to function ratio in all driving styles and moods yet amazingly with no loss of economy, in fact an improvement. A word too about after sales support, first class. Would recommend product and company anytime.

  • Liam from Toodyay, Australia with a Hyundai i30 1.6 CDRi 116 said:

    I have been using CHIP Express in my Hyundai i30 1.6 CRDi for over three years now and I can thoroughly recommend them. I installed the module into my i30 from new after an initial 5,000km of run-in. The improved performance is outstanding, with improved fuel economy to boot. I live in Australia and do a lot of long distance country driving often in conditions of extreme heat and my car has ran flawlessly. Furthermore, installation of the unit was foolproof with step-by-step instructions and can be removed easily prior to dealer servicing. Warranty intact! On long stretches of country road the performance increase means overtaking road trains and the like is now effortless. The fun factor on winding roads means that I still enjoy my car after three years of driving it. In fact, sometimes it feels almost like to much performance for the car. Almost. Fortunately, the ability to adjust the required performance is useful. After initial trials, I settled for somewhere in the middle, in terms of power produced. This seemed to provide me with a good balance of performance and improved fuel economy. Though, lately I have moved things up a notch and enjoying the benefits. Fuel economy has improved noticeably, somewhere between 5.2-5.4L/100 km with all types of driving. After 100,000 km of driving the saving on fuel has meant that unit has paid for itself, and some; this is based on comparing the first 5,000 km without the unit installed in combination with reports from other i30 users. All up, anyone considering installing ChipExpress into their diesel Hyundai should not hesitate. It’s a fantastic product and the Team there have been most helpful. I have just purchased a new BMW and I can already feel another visit to ChipExpress is imminent!

  • Joseph from Colwyn Bay with a Audi A6 MK4 3.0 TDI 245 said:

    Since fitting the CHIP Express device my 2013 Audi A6 3.0 Quattro is now how it should've come out of the factory - better throttle response, quicker, and with a significant improvement in fuel economy. I'm running the device in +2 and the results are excellent!

  • Rex from Devizes with a BMW F15 X5 xDrive 40d 313 said:

    Just a note to say how pleased and impressed I am with your continuing great service. I have just taken delivery of my 3rd unit having 2 previous ones on my BMW X3 and my wife's Volvo XC90. I would not now contemplate motoring without one as the improvement in performance and efficiency is quite marked and makes driving all the more enjoyable. On the question of service this is extremely prompt and I have no hesitation in recommending your product to anyone.

  • Gerald from Telford with a Ford Mondeo MK4 2.0 TDCI 140 said:

    I ran my last Ford Mondeo for over 150,000 miles over the last 6 years with a CHIP Express unit fitted. The car completely changed from being sluggish and thirsty to being rapid and economical. The fuel economy went from an average 39mpg to 54mpg at 70mph. What a brilliant bit of kit! I have now changed to a Mondeo 2.0 TDCI 163PS which simply does not live up to the manufacturers claims, so once again I will be fitting one of your chips and look forward to the transformation!

  • John from Chersterfield with a VW Transporter T5 1.9 TDI 102 said:

    I would just like to thank you for your quality service and product. I have a 1.9 TDI VW based motorhome and tow a small Suzuki Alto for travelling when parked on site. Prior to fitting the Chip it was a little under powered, well no more! There is a significant improvement on towing, less gear changing and better efficency. I would like to recommend your product wholeheartedly.

  • Praem from Bangkok, Thailand with a Toyota Land Cruiser 4.5 D-4D 286 said:

    I personally enjoy using your tuning chips on various vehicles I run. I have tried other brands of chiptuning but none of them can compare. My Land Cruiser 4.5 D-4D's soot issue has been solved by your product and of course more power is developed. My Porsche Cayenne Diesel II 3.0L 245 shows a great increase in performance - especially torque. Moreover, my F10 BMW 520d 184 now enjoys much smoother gear changes. Right now I'm about to try one of your systems on my Mitsubishi Triton 2.5 Di-D 178 and will report back the good news. Many thanks for your continued best efforts!

  • Lee from Bromborough with a Mercedes W204 C220 CDI 170 said:

    Recently bought the chip for Merc C220, super impressed! Drove down to London this weekend at 67MPG, no lag, improved performance - exceptionally pleased. A great product that's paying for its self already!

  • Jim from York with a Kia Ceed 3 1.6 115 said:

    You may be interested to know that with the tuning box disconnected the best local running mpg was 50, where as with the unit connected it is normal for me to see 55/56mpg. It does better on long runs when I have seen up to 60mpg cruising at 70mph. Many thanks!

  • Brian from Chelmsford with a Jeep Cherokee MK3 2.8 CRD 163 said:

    Thank you for an excellent service. I fully endorse the views of other customers regarding the claims of this product. One may or may not find a rival product as good as CHIP Express. One certainly will not find a company that delivers better customer service. In my opinion, the measure of a good company is how well they deal with any unforeseen problems. They were as good as their word, I can not recommend CHIP Express highly enough.

  • Simon from Melbourne, Australia with a Toyota Land Cruiser 4.5 D-4D V8 Auto 272 said:

    As of today, the Chip has been installed, and I must say that I am VERY IMPRESSED with the improvement in torque using the standard settings. There is no soot and no engine lights. Finally, I commend you on your packaging. It will take strained eye to even notice this device lurking in my engine bay!

  • Steve from Houghton-le-Spring with a Audi Q7 3.0 TDI 240PS said:

    I would just like to thank you for prompt delivery of tuning box, as you said it was easy to fit in minutes. The car now pulls and drives a lot better through the gears with no flat spots or turbo lag.

  • Barry from Bunya, Australia with a Toyota Land Cruiser 4.5 D-4D 205 said:

    Thank you for the speedy delivery, the chip arrived a few days ago and yesterday was my first day driving with the standard setting. The improved power response from 2000rpm quite noticable and a great improvement with overtaking or when going up and down hills. Today I upped the setting to max and the surge between 2500rpm all the way past 4000rpm is fantastic! I have the standard Toyota catalytic convertor but after that the exhaust is now 3 inches in diameter with no muffler and that's it.

  • Steve from Exeter with a Ford Kuga MK2 2.0 TDCi 140 said:

    Thank you for the prompt delivery. Fitting to my 2013 Kuga took minutes, the chip is working perfectly with no faults and has made such a different to the drive and pulling power. Economy was an average of 35mpg but after a run now it's now showing 42mpg so very happy!

  • Rick from Macclesfield with a Mercedes E-Class E350 CDI 265 said:

    Thank you for an exemplary service and rapid turnaround. I have to say that the courtesy and quality of service I have experienced over the years should be an example to any company wanting to succeed in business. Many times I have been frustrated and hugely disappointed when addressing a company through their "Customer Service Department", usually, the bigger the company, the worse service you receive. Dealing with Chip Express is definitely a breath of fresh air!

  • Malcolm from Herne Bay with a Rover 75 2.0 CDT 115 said:

    You may pay more for the CHIP Express system but its worth it, nothing but top results! Very smooth power delivery which comes in much earlier, no smoke, improved economy and so easy to fit, I have mine in a space in battery box. I will run the chip as supplied for a while then see about a slight tweak upwards, but for such a heavy car it sure can move now!

  • Steven from Tranent with a Isuzu Rodeo / D-Max 2.5 Twin Turbo 163 said:

    Thought I would provide some feedback after fitting my tuning box to my 2014 Isuzu Dmax 2.5 Utah. After fitting, what a difference in power! I have had Fords and Toyota pickups in the past and I feel the Isuzu is quite slow at certain points for pulling away. It has now been corrected and you feel the extra torque. I have just returned from a fishing holiday in the north of Scotland, a 500 mile round trip with a good mixture of dual carriage ways right down to single track roads. Averaging 60 mph my MPG was 40, I was expecting 30-35. Very impressed, never had that sort of MPG from a pickup before. This is my second purchase from you guys and would highly recommend to anyone thinking about it.

  • Antonio from Miami, USA with a Volvo Penta D6 435 Marine said:

    We installed the chip on our Tiara Sovran 43 boat with twin 2011 D6-435 engines. Although mechanically perfect with a clean hull the boat was not planning in the Caribbean waters, maybe because the warmer water is less dense? Either way with the chips the boat now planes very quickly, top speed has risen by 2-3 knots and fuel comsuption has fallen when cruising at 27 knots / 3100rpm by one galon/hr per engine.

  • Stephen from Cleckheaton with a Fiat Ducato 2.3 130 Multijet II Euro 5 130 said:

    Just fitted the chip to the motorhome WOW. MAGIC. FANTASTIC. Does what it says on the box. I will definitely recommend to friends and family thanks guys five stars!

  • Darren from Hilmarton with a Land Rover Discovery (2) TD5 138 said:

    Just a quick note to say thank you for the service I received. I was able to correctly fit the unit using the detailed photo instructions. Once the installation was complete it was test drive time.... WOW! What can I say? A night and day change! The TD5 is now stunning to drive, power exactly as it should be. I will recommend CHIP Express with pleasure, thank you for making my drive great!

  • Koutsoudis from London with a BMW 3 Series E90 320d 163 said:

    A Very easy installation. Feels like I am driving another car. Great job guys and just one more word... PROFESSIONALS!

  • Jeff from Gateshead with a Alfa Romeo 159 1.9 JTDM 150 said:

    I had the chip professionally fitted by an Alfa Specialist. If I'm getting more MPG thats great but we bought the chip for performance. Talk about doing what it said on the tin, it's like we've fitted a new engine! Thanks!

  • John from Stoke-on-Trent with a Mercedes ML270 CDI Auto 163 said:

    We bought one of the units for our Mercedes ML about 4 years ago. It has made a noticeable difference to the performance - the car always seemed to under-perform for its size before it was fitted and this has improved it considerably, thank you.

  • Paul from Watford with a Volvo XC70 2.4 D5 163 said:

    I have today received and fitted the CHIP Express kit and I was delighted with the improvement it instantly made to my Volvo XC70. It has saved me thousands of pounds, because now I don't need to buy a new car, this has effectively made mine into a new car, also must commend you on a excellent service, prompt delivery and very helpful staff.

  • Mustafa from Gabala, Azerbaijan with a Jaguar X-Type 2.0D 130 said:

    I was sceptical about the achievement of your product.... HOWEVER after use I am very happy! A quick 30 minute test drive and my Jaguar runs better then ever, even at an altitude of 2,569ft. I can now fully endorse your chips!

  • Brian from Wingate with a Audi A4 MK4 2.0 TDI 170 said:

    I today received the chip I ordered for my sons Audi A4 Quattro. What a great and efficient firm you are to do business with. My son informs me that the chip was easy to install and he is very pleased with the resulting performance.

  • Stuart from Newcastle with a BMW E60 535d 286 said:

    I had this chip on the wife's Golf 2.0 TDI MK6. It made a massive improvement to performance and MPG, especially on long motorway drives, however considering she only did a 4 mile combined trip to work it was pointless, so I decided to have the chip reprogrammed for my BMW. On the 535d it has given me instant throttle response, normal drive mode is very smooth and responsive without flooring the pedal and sports mode is like being on a runway train. Absolutely delighted yet again, thank you.

  • Neil from Barnsley with a Mitsubishi Shogun 2.5 TD Sport 115 said:

    I do a lot of motorway driving and felt the difference straight away. The pick up is now immense without requiring much throttle to accelerate. I am also not dropping down to use lower gears as much anymore. Thanks again for the easy set up photos, plugging in the chip took me just 5 minutes!

    Fitted unit over 3 years ago on BMW 5 series M sport Touring 20d. Consumption 48-56 mpg, mid range grunt and acceleration brilliant on a vehicle with 130,000 on the clock. Have to teach right foot I am no longer a teenager!

  • Justin from Congleton with a BMW X3 E83 3.0sd 286 said:

    First class device with the support to back it up. I have a CHIP Express box fitted to my BMW X3 3.0sd 286PS. The tuning box makes the cars power delivery more linear and irons out the flat spots. There support service is excellent and will bend over backwards to help you out. I highly recommend CHIP Express for your tuning box needs.

  • Jean from Hollywood, USA with a BMW X5 F15 xDrive 35d US Spec 259 said:

    I bought a 2015 BMW X5 35d recently, I love it. After a week I decided to order a CHIP Express. BEST decision ever! INCREDIBLE torque and power increases, on top of that I managed to make a trip of 1400 freeway miles with 2 1/2 tank of gas with 4 adults and luggage. WOW! I would recommend this product to anybody, 5 STARS!

  • Jai from Leeds with a VW Passat MK5 1.9 TDI 130 said:

    A definite improvement in mileage and performance. I drive for work, previously my trip was costing me £42, after installing this its now costing me £35. Very happy with it and happy with your service!

  • Paul from Hockley with a Nissan Navara MK2 2.5 dCi 174 said:

    I fitted one of your chip sets to my Nissan Navara 2.5 dCi approximately 2 years ago and noticed a massive difference in the way the truck drives, I am very pleased and have subsequently told many friends who have since purchased chips for their vehicles. Keep up the good work!

  • Roy from Sydney, Australia with a Ford Ranger MK5 3.2 TDCi 200 said:

    I've received my chip, thanks for that. Easy to fit and a noticeable difference to my Ford Ranger 3.2, especially in the lower gears. I am now really enjoying the smoother acceleration!

  • Darren from Perth, Australia with a Land Rover Discovery (2) TD5 138 said:

    I installed the module and road tested, it has a very noticeable performance enhancement, I can safely pull out onto the highway, as it will now put foot. We went out on camp in the dunes last week, Bridgestone A/T tyres set at 18 psi, it now ploughs through all the soft sand, where before it would sink in and blog down or struggle. The difference in torque is truly worth every cent!

  • Vince from Marana, United States with a VW Passat MK7 2.0 TDI 140 said:

    I was skeptical about purchasing a "off shore" performance chip. It's been installed for almost 2 weeks now. Right off the throttle lag was almost gone and while not a race car acceleration was noticeably better! My economy went up a solid 3-4 mpg (I drive the same route most everyday). Right now my 2014 Passat TDI SEL is so close to averaging 50 mpg (46-47 by filling to the brim and dividing miles driven by gallons used) it's almost frustrating. But this kind of frustration is great! Best money I've spent on my VW yet!THANKS.

  • Frazer from Driffield with a Volvo V60 2.0 D3 136 said:

    I am chuffed to bits, a fantastic service from CHIP Express. This is my second unit after taking advantage of the trade in offer when I changed cars. The first unit was faultless for 130k miles on my Insignia, I traded in for a new kit for my Volvo V60 D3. Very impressed with the performance and fuel economy increases on both cars. I cant thank them enough, great product and great service, I will most certainly be getting another kit when I change cars again.

  • Daniel from Brighton with a Ford Mondeo MK4 2.2 TDCi 175 said:

    It took me minutes to install from start to finish, acceleration is significantly quicker with a huge power increase. There are no flat spots in first and second gear. It is smoother to drive with improved economy of around 15%. On the motorway overtaking is now effortless. I am impressed and delighted with the tuning system.

  • Neil from Burbage with a VW Passat MK7 2.0 TDI 170 said:

    I have one of your kits on a 2012 Volkswagen Passat 2.0 TDI 170 and a 2013 Audi TT 2.0 TDI 170. I would just like to say how pleased I have been with your products. Both my wife and I noticed a great improvement, the increase in both power and fuel efficiency is phenomenal!

  • Keith from Chepstow with a BMW F20 120d 184 said:

    I drove some miles to Birmingham to fully test the system. The extra BHP was evident and the torque was also much better. The upping of torque allowed me to use taller gears and still get the power. The most noticeable thing was how smooth it all felt. Like driving a different car. Remarkable difference! I am very impressed, well worth the money! FOLLOW UP: I have driven about 500 miles since fitting the chip and my MPG is slowly creeping up, at present is 45mpg. The engine seems much quieter and the lower end torque means I can use a gear or two above what I would usually, this combined with the improved acceleration make this a product I would recommend this to anyone!

  • Simon from Stamford-le-Hope with a Toyota Hilux MK6 3.0 D-4D 171 said:

    Purchased a chip for my 2011 MK6 Hilux and I am very pleased. I've noticed a lot more power, its quieter and the automatic box also seems smoother. Delivery was next day and the information on how to install was very well laid out. I would highly recommend it to anyone that was thinking about it. Thanks CHIP Express, a job well done!

  • Vic from Dianella, Australia with a Chevrolet Colarado 2.8L 200 said:

    I was looking to improve economy and reduce turbo lag. With the CHIP Express fitted I gained 1.5 litres per 100kms better fuel economy if solo and when towing a 2 tonne trailer I appreciated the noticeable power improvement, 25% at least. The reason I wanted the chip was for fuel economy and at present I am getting 15% more on average with regular city and suburban driving.

  • Shaun from Boughrood with a Fendt 820 Vario 6.1 R6 207 and Fendt 724 Vario SCR 6.1 237 said:

    I would just like to say what fantastic service i recieved from CHIP Express. I have been using two chips for several years now on my tractors and I have to say they have been faultless, with improved performance and fuel economy. After many times of taking the chip on and off one of my workman had managed to damage the cable, but this was not a problem as CHIP Express soon had me a replacement which was supplied free of charge under warranty. NOW that's what I call looking after your customers. Absolutely first class, helpfull and professional. Exceptional service from a top firm!

  • Alan from Telford with a BMW X3 F25 xDrive 20d 184 said:

    I just wanted to pass on a little (good) feedback. I fitted the unit as soon as it arrived, and after a little hiccup (100% my fault) it’s working perfectly. My onboard commuter was giving me a reading of 44mpg before the unit was fitted. Now 200 miles later I’m getting 55mpg. A fantastic result that I hope to improve upon as I bought the unit for better economy. Thanks again for your help and a great product!

  • Gordon from Redhill with a Dacia Sandero MK2 1.5 dCi 90 said:

    I have a 2014 Dacia Sandero Stepway which is fitted with the Renault K9K 1.5dCi 89PS 220Nm engine which is also fitted to some Renault and Nissan vehicles. My previous car was a petrol turbo with 147PS and 210Nm torque so my new lack of power was obvious but as far as torque was concerned I was already 10Nm up in standard form. I had heard about diesel tuning boxes but have to admit I was extremely sceptical about them. Being an ex-racer and ‘old fashioned’ tuner I was used to increasing performance with cylinder head, camshaft, induction and exhaust modifications but as this car was my first diesel I was willing to try this ‘modern gizmo’. I ordered a Chip Express tuning box for my car which arrived the following day. Fitting instructions were comprehensive, easy to understand and tailored for my engine (not like a lot of generic instruction sheets you see). Actual fitting time was less than the time I took reading the instructions…it’s that easy however due to my OCD about engine bay tidiness I took a further 10 minutes making sure everything was neat, tucked away and tidy (but that’s just me). I left the jumpers set as supplied and the performance improvement was immediately noticeable as was the engine noise which was significantly reduced. The engine immediately felt livelier and the torque increase was impressive. It’s difficult to express on paper, you really have to feel it, however, there is a low speed steep hill which I travel up every day. Before ‘the box’ it was an asthmatic 2nd gear hill with the engine getting you there but don’t expect much more. Now, the car will easily pull up the hill in 2nd and will accelerate whilst doing so. That hill sold it for me and told me that the money was well spent. As far as fuel economy is concerned the engine is quite economical in standard form with 60mpg achievable however ‘the box’ made 70mpg easily achievable on my daily commute into London. I have a ScangaugeE device which shows, amongst other things, journey mpg. After a month or so the urge for more grabbed hold of me and following a quick email to the ever so helpful people at Chip Express I was assured that pushing the jumpers to the maximum would have no adverse effect on my engine. Within minutes of receiving that email I was under the bonnet and moving the jumper plug straight away to its maximum position (although I was told to do it in stages). All I can say is ‘impressive’. The hill I mentioned earlier is now a 3rd gear and accelerating hill AND crazy as you may think fuel economy has improved yet again and now 75-77mpg is achievable on my daily commute. The car is a lot more driveable with fewer gear changes and as a result a much more relaxed drive. All in all it’s a great bit of kit and I challenge anyone not to say they’re impressed by the increase in performance.

  • Richard from Jogjakarta (Indonesia) with a Ford Ranger MK5 2.2 TDCi 150 said:

    Done... fitting was easy, no problems and no engine check lights. A test drive proves your chip works well, gear shifts are smoother, no turbo lag, and higher gears now work at low rpm which is ideal for the city. I can also reach 120km/hr much faster and my 6th gear still has a lot of power. More then happy using this chip and thank you for your support.

  • Kristian from Marbella, Spain with a VW Golf MK6 2.0 TDI 140 said:

    I just got back from a European tour of 5000km and that GOLF drives better than ever. I have now enjoyed 6 months of noticeable improved economy. Torque is now effortless up to 3000rpm and I now do 17km/l when pushing it and on cruise control at 100-120kmh somewhere between 22-26km/l, crazy when my BMW M3 is struggling to do 9km/l. I highly recommend the chip. I am one happy bunny!

  • Richard from Christchurch with a John Deere 6330 4.5 4V R4 CR 105 said:

    I just have to write to let you know how much better my JOHN DEERE 6330 tractor is running now your chip is fitted. The power upgrade is astounding and I can now pull heavy loads without changing down so much. I would recommend your company to any farmer with confidence. Cheers!

  • John from Goole with a BMW F30 330d 258 said:

    I originally fitted my chip to my 325d BMW, after sending it back for re-programming it was then fitted to my BMW 330d, I found the power and fuel economy to be exceptional. I am now changing to a VW Amarok 2.0 BiTDI due to work and I have just sent it back for re-programming again. I have found the service Chip Express provide to be first class in the years I have been using their chip and have just recommended them to a work colleague, who is seriously considering fitting one to his car.

  • Chris from London with a Audi Q7 3.0 TDI 240 said:

    I sent my chip back for reprogramming as it was fitted to my BMW and wanted it on my Q7. This turned out to be a speedy, hassle-free process and all done very professionally. The chip arrived within a few days, complete with fresh Audi cables in the box, like new. I knew what to expect as I had had the chip fitted to my other car. Once fitted, the amount of torque which the chip delivered over the standard was obscene. The Q7 as standard is a torque powered beast, but with the chip it could start the world turning again, but the nice thing is that this torque was still delivering further up the rev range giving me much more drivability, over taking and towing power. For those of you hesitating and thinking of upgrading to a tuning chip, I can highly recommend it, it’s a very quick, clean, easy process to fit and gives an instantly different feel to your car. Don’t think, just get one and you won’t be disappointed! I even have one fitted on my Wife’s MK7 Golf and it’s a dream to drive also. A great product indeed!

  • Adrian from Huddersfield with a Kia Pro Cee'd 1.6 CRDI 115 said:

    I recently purchased a 2010 Kia Pro Cee'd only to discover it had the detuned 115PS 1.6 CRDI engine which felt flat compared to the 126PS 1.6 CRDI model my partner owns. I have now fitted a CHIP Express tuning box and the car has been transformed. The acceleration and mid range torque is greatly improved and it now feels lively unlike before. Overtaking is much improved as is 3rd gear acceleration, which is especially useful on slip roads when joining fast moving traffic. I have yet to check the overall MPG change but so far it would seem less fuel is being used. Thanks very much!

  • Chris from Beechworth, Australia with a VW Golf MK5 2.0 TDI 140 said:

    The cost of diesel is on the rise which is why I chose to get a one of your chips, now in combination with a 2.5" s/s mandrel bent turbo back exhaust, EGR delete kit, catch can fed into exhaust and high flow inlet I get on average 4-4.9l/100km with more torque and HP than I could ever need. The CHIP made the engine so much smoother and only took a handful of minutes to fit. Thank you from my family and myself, we are 100% satisfied and recommend you too choose CHIP Express!

  • Keith from Brisbane, Australia with a VW MK5 Jetta 2.0 TDI DSG 140 said:

    Your chip has transformed my Jetta into a totally superb driving machine. I now wonder why VW engineers fail to attain the same standard of performance achieved with your system. There is no turbo lag anywhere in the rev range, not even from the starting grid and no sharp gear changes. The power band is right across the rev range. The economy has improved from 5.8L/km to 4.8L/km on the open highway. The engine is smoother and quieter. Summing up, it is now a vehicle I want to drive. I have four sons and each has agreed that your chip has made a remarkable difference. Thanks for the fun!

  • Neil from Burgh Le Marsh with a Ford Kuga MK2 2.0 TDCi 140 said:

    May I say how pleased I am with the CHIP Express module I fitted to my Ford Kuga a few weeks ago, it has made such a difference as well as super smooth running. Many thanks for your assistance and a great product!

  • Mike from Siilinjärvi, Finland with a BMW 3 Series E90 320d 163 said:

    I thought about this purchase for about a year. Since fitment I'm so happy, the car is totally different in a REALLY positive way, my 4 cylinder engine now has 6-cylinder torque output, as a result the throttle response is immediate and my consumption has also dropped by 0,9l/100km, now that's impressive! Keep up the good work guys.

  • Murray from Glasgow with a Audi A4 MK4 2.0 TDIe 136 said:

    I had a chip in my previous Audi A4 2.0 TDIe 136 and what a fantastic difference it made to the car. Just changed to an A6 Allroad 3.0 TDI 240 and returned the chip from the previous vehicle for remapping. I sent it off on Saturday morning and the postman delivered it back on Tuesday morning. What a service! Other companies should take note on how it can be done. I refitted the chip and again what a difference. I cannot recommend the product and the company enough. Thank you.

  • Harold from Aberdeen, USA with a Mercedes / Sprinter USA / 3.0 CDI / V6 / US and CA Spec 191 said:

    We did a quarter mile speed test before installing the chip, the speed was 59.5 MPH in 23.1 seconds, the average MPG for highway driving was 14.2. We then installed the chip and did the same test, the quarter mile speed improved to 64MPH and the quarter mile time is now 21.9 seconds, MPG was up to 15.3 - remember this motorhome weighs about 12000 pounds so we figure the horse power increase is at least 40! We are impressed.

  • Andrew from Harpenden with a Land Rover Discovery (2) TD5 138 said:

    Fitted the system in minutes as the instructions were very clear. I then went for a test drive and “WOW” what a difference! It feels like it’s had a shot of caffeine. Very pleased with the system as well as receiving good service and advice on the purchase.

  • Robert from Flynn, Australia with a BMW E53 X5 3.0d 204 said:

    Makes a great difference to take off, much smoother and more responsive. Bang for buck this is great!

  • Ian from Peterhead with a Fiat Fiorino / Qubo 1.3 Multijet 75 said:

    Excellent! Engine felt choked before and frustratingly sluggish. Engine now revs freely and pulls much harder... brilliant product!

  • Ian from Fishcross with a Vauxhall Antara 2.2 CDTI 163 said:

    Very easy to install on my 2015 model, took me less than ten minutes. What a difference! All round improvement, money well spent. Thank you Chip Express!

  • Mark from Reading with a Renault Laguna III GT V6 3.0 235 said:

    I purchased one of your systems for my Renault Laguna GT Sport Tourer 2.0 dCi 175. I was impressed with the car but heard about your product and decided to give it a try. The fitting was simple and I left it on factory settings. Instantly I noticed an increase in power and drivability and with us living in the country the extra overtaking advantage on B roads was worth the price on its own. Four years on I decided to change my car to a Renault Laguna Coupe 3.0 dCi 235 GT and decided that with the extra standard power and torque of the new 3.0 dCi V6 I would not fit a CHIP Express box to my new car, or so I thought! Having taken the chip off of my old Laguna to take it to the dealer for part exchange it was almost like driving a completely different car. The power and smoothness I had taken for granted had gone and I just couldn’t believe the chip had made such a difference. I arrived home with my new car and the first thing I did was contact CHIP Express to arrange to have my chip changed over to the 3.0 dCi. This in itself was a quick and easy process and the new chip was fitted following the excellent photographic instructions. Left on standard settings I did some before and after testing on some quiet country lanes and was amazed. I have had the chip on for over a month now and the wife still wonders what the big grin is about as we drive around. I will never have another diesel car without fitting a chip box and my father was so impressed he has purchased one for his motorhome. Thanks for a great product and service!

  • Tim from Thefford with a John Deere 7450 Harvester 13.5 R6 said:

    I would like to the time and say how fast and brilliant your service has been. I run three of your units and have been very pleased with them. Many thanks again.

  • Ian from Colchester with a Volvo XC90 2.4 D5 185 said:

    Works well, turns a slow beast of 2 Tonnes from a 0-60 at 11 seconds to a 0-60 in around 9 seconds, with my driving style economy went from 27mpg to 30mpg. I've bought a new car and not worried about performance because I know I can fit one of these and performance will be just fine.

  • Enrique from Miami, USA with a Hyundai Veracruz 3.0 V6 240 said:

    My biggest concern was to reduce or eliminate the hesitation from a stand still. Hesitation was considerably reduced, on a scale of 1-10 I would say 7. Fuel economy is a byproduct for me, but was surprised to see consumption go from 14.5 L/100km down to less than 10.0 L/100km under normal driving conditions!

  • Ian from Dereham with a Chrysler Grand Voyager 2.8 CRD 163 said:

    You will not get a much simpler kit to fit, the performance and MPG gain is well worth the outlay. It's like driving a different vehicle, so much more torque lower down the rev range - a must for any Voyager RT owner!

  • Hugh from Ashtead with a BMW E60 520d 163 said:

    Am very pleased with the product bought for my BMW 520d. The claims you make are all borne out by the results I am getting. A really good car is even better as a result. Thank you also for your prompt service.

  • Leighton from Nottingham with a Mitsubishi Shogun 2.5 TD 115 said:

    Just wanted to send a bit of feedback regarding the unit I fitted to my Shogun Sport 2.5 TD. The unit was ordered around 2:30 one afternoon and was delivered at 7:30am the next morning, absolutely fantastic service! I fitted the unit on my lunch break at work and the installation was incredibly simple. The difference is fantastic, the car revs smoother and higher, no need to rev the engine a little bit whilst pulling away now as it feels like the power is instantly available from a standstill. There is definitely a lot more power and torque in every gear and the cars performance has been totally transformed. I honestly can not fault the unit or the service that Chip Express have provided, thanks!

  • Andrew from Southwell with a VW Touareg 3.0 V6 TDI 240 said:

    Can I say what a brilliant piece of kit the tuning box is. It resolved the flat spot that seems to come with the engine's standard set up and gives a great surge of extra power, and yet I return about 2mpg better fuel economy. Brilliant!!

  • Matthew from Woodley with a Volvo S40 2.0d 136 said:

    Volvo 2.0d 2005. I had a box for my Golf Mk4 GTI 150PD from Van Aaken and it was good. I have just gone from a 300bhp Skyline to this diesel Volvo and was sad to miss the power. I looked about and bought the Chip Express device. It really is amazing. My Volvo would give my old Golf a run for its money. Mpg standard was 44mpg (driving normally) and is now 52mpg! Awesome Product!

  • Pedro from Colne, Lancashire with a Alfa Romeo GT 1.9 JTDm 150 said:

    Since I installed your product the mpg improvement and the ease to drive (due to better torque and increased power) were immediate. Thank you very much for giving me such performance gains without changing the car!

  • Dave from Plymouth with a Toyota Corolla 2.0 D-4D 90 said:

    Just to say how pleased I am with the product, I went from Plymouth to Portsmouth, the mpg before fitting the Chip Express device was 46.8 mpg - we made 60 mpg on the 170 mile trip. We did some short runs while there and a return trip yesterday, we averaged 58.2mpg on the 425 miles covered. Many Thanks! A Very Happy Customer.

  • Nick from Tamworth with a VW MK4 Jetta 1.9 TDI 105 said:

    We recently bought a caravan and collected it with our car but when towing realised we needed more power, a friend told us to use 'Chip Express'. I bought one and fitted it last week, went for a test drive and 'WOW' - the power is amazing now. We towed the caravan earlier today and noticed it was much easier to pull and the fuel economy was much better, when we picked it up we got 33mpg but now we're getting 40mpg. We are very impressed, especially as we ordered the box at 4:30pm on Friday and received it Saturday morning!!

  • Timothy from Stoke On Trent with a Audi A4 MK3 3.0 TDI 233 said:

    I ordered my Chip Express for my 2007 AUDI A4 3.0 TDI on Tuesday afternoon, to my surprise it arrived the next day at 08.30; fantastic service. I fitted it that evening in less than 5 minutes thanks to the easy and accurate instructions and photo's. The difference is staggering; the torque is huge giving blistering performance with no black smoke. Great product!

  • Mike from Dumfries with a Massey Ferguson 5465 6.6 R6 129 Perkins said:

    The chip was set as it came from yourselves and has been working well. The tractor has hauled many thousands of gallons of slurry with the system fitted. The operator has been delighted with it! Many thanks!

  • David from Darlington with a BMW E90 320d 177 said:

    Wow, I just cannot believe the difference. It is like driving the 3lt diesel with 50mpg+. I don't know how you have managed it and it shows that for whatever reason BMW are not getting the best out this engine in std tune. Thanks very much and have recommended to all my diesel driving friends.

  • Steve from Auckland, NZ with a Land Rover Discovery (2) TD5 138 said:

    Can't get over the difference the chip has made to the performance of my 2003 Land Rover Defender Td5, it's travelled 200,000 ks and this chip has given it a new heart, the power is incredible and you wouldn't even notice that I'm towing a caravan. It arrived at my house in New Zealand seven days after placing the order and fitting was simple. I highly recommend "CHIP EXPESS".

  • David from Woodbridge with a Chrysler 300C MK1 3.0 CRD 218 said:

    Thank you for prompt delivery. Spent some time reading my instructions then went ahead and fitted the chip to my Chrysler 300 CRD... the power now feeds in strongly from 1500rpm and use of kick down on the auto is not really needed. Your chip has completely transformed the car into a refined high speed cruiser. I love it, thank you very much.

  • Robin from South Yorkshire with a BMW E71 X6 30d xDrive 235 said:

    I know that you have a considerable number of happy customers but I would just like to add to that growing number! The ease of fitting was incredible (literally minutes as you promised!) and the resulting improvement in the engines low end performance is worth every penny.

  • Martin from High Wycombe with a Alpina D3 2.0d 200 said:

    I used your chip on my BMW E46 330d for the last few years and recently returned it to you for adaption on my Alpina D3. I now have it fitted and am once again very happy with the gains, my MPG is also much easier to maintain at around 47mpg extra urban. Keep up the good work guys!

  • Barry, Algarve region, Portugal with a Peugeot 407 SW 1.6 HDI 109 said:

    Just to let you know I have fitted the unit to my Peugeot 407 SW 1.6 down here in the Algarve, where it is warm and sunny, and, as with our Volvo D5 system, simple to fit, the instructions are excellent and it runs beautifully. I initially bought a cheaper unit from another company, but it did not actually work! This is my second Chip Express unit and again the results are remarkable, much better response, a significant increase in power and better economy, in my view an outstanding unit! Thanks again.

  • Paul from Coventry with a Land Rover Range Rover Evoque 2.2 SD4 190 said:

    I purchased one of your units to fit onto my Range Rover Evoque last year and I must comment that I am really impressed with the product. Many thanks!

  • Paul from Newcastle Upon Tyne with a Audi Q5 2.0 TDI DSG 170 said:

    I purchased a chip from you early last month. Sadly I fell and broke my ankle the day after I fitted it so I couldn't drive for 5 weeks. I would just like to say Wow! It has totally transformed the car. In particular the slow speed driving is much smoother, the car does not hunt for gears as much and the economy is amazing. I saw 44.5mpg on my 35 mile commute to work yesterday. The best money I've ever spent on a car!

  • Robert from Brierley Hill with a Mercedes C200 CDI W204 136 said:

    I can not believe the change in my car with this chip. Power is just unreal to the standard setup on my C200. Mercedes need to improve the programming on there cars. This diesel chip is well worth the money paid.

  • William from Dublin with a Nissan X-Trail 2.0 dCi 173 said:

    Just fitted the new box you sent me. What a difference it has made... the power is unbelievable, acceleration is better, mid-range it is so quick no matter what gear you're in and top speed is much improved, fuel consumption is slightly sore when you use full throttle (to be expected), but when driven normally I could not believe how much more economical it now is! I will be recommending it to my friends. I would like to thank you for the assistance you gave me when I was fitting the box... I am very impressed!

  • Christopher from Bridgend with a Ford Focus MK2 1.8 TDCi 115 said:

    I have put the chip from yourselves into the car, it was simple and done in minutes. The power I got was great, you could feel the car pick up speed much better and, my fuel to miles has gone up also, thanks.

  • Michael from Northwich with a Vauxhall Insignia 2.0 CDTi 160 said:

    Hi guys, it's me again with a red face. Here's a good tip, don't try a fit a chip on an icy car when it's freezing cold and your fingers are as flexible as lead pipes. Go for a drive to warm the car up, leave it 5 minutes and have a cup of good old tea to warm the hands, then hey presto the chip will fit first time. Just been for a drive with the system fitted and WOW it is very impressive, it sounds quieter, feels smoother and the performance is terrific. Well done!

  • John from Ashton Keynes with a BMW E90 335d 286 said:

    Just a quick note to say many thanks for the prompt delivery. I fitted the device this afternoon and am very pleased indeed with the results - as you said, the throttle response is much more linear and consequently the car is significantly easier to drive. My wife has just been out for a drive and is also delighted with the results, so many thanks.

  • Adrian from Farnworth with a Citroen C5 II 2.0 HDI 136 said:

    I recently fitted a tuning box from Chip Express. I have since done over 4000 miles. What a difference this little box has made... I am averaging 50.4 mpg at motorway speeds, with greatly improved acceleration. Well done everybody at Chip Express... worth every penny!

    Got chipped and so far so good. Torque is noticeably up, much more low rev pull. Economy is also up by 2-3 mpg. Auto box is now even smoother for gear changes. Hope the MPG improves even further as my driving style gets used to the less heavy acceleration now required since chipping.

    My vehicle is 102 HP 2004 Toyota Hilux 2.5 D-4D with 50,000 miles running 31 10/50 15 tyres. Your chip has smoothened out the power very well! It now pulls evenly through the rev range with no excess fuel knock or injector rattle on overrun, no blacking on power from the exhaust. The increased torque means less loss of speed on hills but also you notice the fact that you don't need to change down as much on mountain roads. When I tested this Toyota for the car magazines in 2004 my main gripe was that the long gear ratios were not suited to the short power band on the 2.5 D-4D... but your chip does what the manufacturers should have done by making the engine pull from lower in the rev range... on these vehicles that is a welcomed change to its original characteristics!

    Firstly, many thanks for an excellent product. It arrived the next day in perfect condition. I fitted the chip myself with a little assurance from one of your technicians. After road testing I can confirm all flat spots have now been replaced with silky smooth torque! I would recommend your product to anyone. Thanks again.

  • Don from Auckland with a VW Golf MK5 1.9 TDI 105 DSG said:

    Last Saturday I fitted my new Chip Express system and all I can say is WOW!! It measured up to every aspect that you promoted it on as regards the upgrade in performance. It is measurably smoother, in fact quieter, far more torque, and changes gears much more rapidly... it is very quick now! Cheers.

  • John from Grantham with a Ford Mondeo MK4 2.0 TDCi 130 said:

    Just a quick note to thank you for the swift delivery of your CHIP Express unit. I could not believe it arrived so quickly and also how easy it was to install thanks to the clear instructions. The performance and sheer driveability has been increased 100% with no side effects - it feels like a completely different and much newer car with smooth delivery of power right across the rev range, amazing considering it is six years old and has covered almost 80,000 miles. I will have no hesitation in recommending your product to my friends. Many, many thanks.

  • Chris from Essex with a Audi A4 MK4 2.0 TDI 143 said:

    Hi there, just wanted to say thanks and how pleased I am with my purchase. At the moment the box is still set up on your standard settings, the change from standard is amazing, loads more torque, better throttle response, increased MPG and a joy to drive. Once again many thanks

  • Ian from Darwen with a Volvo XC90 2.4 D5 185 said:

    Having recently bought you product I can tell you this has transformed my vehicle... better MPG, I achieved 32mpg whilst towing my 1500kg caravan. I took the vehicle for its MOT and passed the emission test with flying colours. A better CAR ALL ROUND!

  • Paul from Oxfordshire with a Toyota Hilux MK6 2.5 D-4D 120 said:

    Just a quick note to let you know that your product has made a huge difference to the performance of the vehicle. It has made the power so much smoother over the entire rev range, given added thump when needed, and the economy has noticeably improved after a long run over known mileage this past weekend. Really impressed with the chip and was surprised how simple it was to install, especially as I hate dealing with electrics of any sort being a 'mechanical engineer'. Those sparky things are well left alone usually for us types. Thanks to everyone for their help and advice and prompt service.

  • Kaci from Bridgetown, Barbados with a Isuzu Rodeo / D-Max 3.0 163 said:

    What a change in performance! Seven months of using the chip and I am still enjoying the greater acceleration. With my heavy right foot I am also getting 600Km per tank of diesel - and that's while carrying heavy loads with the air conditioning blowing hard!

  • Steve from Southampton with a Mercedes C200 CDI 122 said:

    First surprise: Having ordered my unit around 4pm on Friday afternoon, I was most surprised and very pleased to receive it first thing on Saturday morning. Second surprise: Ease of fitting. Third Surprise: The overall difference it has made to the car. I own a Mercedes C200 CDI and have always felt that Mercedes got it wrong with this model; however I bought it and am stuck with for the foreseeable future. Your unit has turned it into what it should be, it is now smoother, quieter, responds better and the difference in fuel economy is nothing short of outstanding. Today on a regular trip from Southampton to North London and back I saw the mpg raise from 42.1mpg (average) to 51.2mpg (overall average for the round trip) and apart from road works (M3 & M25) and typical M25 hold ups, I was driving at normal motorway speed (outside lane with flow of traffic).I was that impressed I even stopped in the services on the way back and took a photo of the trip computer display. It was showing the following: From Start 152ml / Av speed 45mph/ 51.0mpg!

  • Alan from Coventry with a Suzuki Swift 1.3 DDIS 75 said:

    Many thanks for your fantastic service! Unit ordered Sunday, delivered Tuesday am!! Unit now fitted and, as promised, the car is transformed. Winding country lanes tackled quite happily in fifth gear. Cruising on much smaller throttle openings and immediate response on acceleration. The car behaves as a mini car should behave. I had some initial doubts about spending quite a large amount of money on this item but it is worth every penny and would not hesitate to advise anyone to do similar.

    Just got back from my first test drive, post-fitting my new Chip Express. Wow! Not that you didn't warn me! Your other customers weren't exaggerating! Yes, yes, yes! Smoother: not even one bolt rattling in the bucket; quicker, smoother change-ups using then previously-irrelevant tiptronic; and that awesome tow from < 1000rpm! More impressed than I had expected, even from your website reviews. Now, to take on my mouthy accountant's Cooper S! I can hardly wait to get it on the freeway to Sydney for a real spin! Now all I need is a radar-detector! Well done, Chip Express!

  • Richard with a Volvo Penta D3 190 said:

    We have fitted one of your systems on Friday to a D3 190. We went on sea trials with the owner and (VODIA) Volvo diagnostics installed. No problems and noticed a much smoother acceleration. Also the engine ran much sweeter and got to its top speed quicker.

  • Richard from Washington USA with a Mercedes R320 3.0 CDI 215 said:

    I purchased an identical chip from you about 5 months ago after being less than impressed with my recent Mercedes R320 CDI performance. Well your chip made THE difference! I purchased a second R320 about 4 hours ago and am ordering a chip for that car before I even get the car next week! My brother-in-law also will be purchasing one from you in the near future! Thank you so much! FINALLY a device the delivers as promised.

  • Daniel from Co. Limerick Ireland with a Ford S-Max MK1 2.0 TDCi 140 said:

    Just here to say I got my chip today. It is true what they say; my car was nice to drive but now it's magic! Much quicker and changing up gears faster. Thanks Chip Express, keep up the good work!

  • Dennis from USA with a Mercedes ML320 BlueTEC 215 said:

    I just arrived back from a long trip... the results are simply amazing - far better than my best expectations. I got as high as 37 mpg on one segment of 250 miles on a four lane road and 36.7 on a 740 mile leg. Overall, I drove over 2500 miles and averaged 33.7 mpg which includes a lot or city driving. Driveability is unchanged or if anything, improved. Before, there was a turbo lag that was annoying at times. Thanks again for your help. Your device is superb.

  • David from Ryton with a VW Golf MK5 2.0 TDI 140 said:

    The chip is amazing! Just plugged it in this afternoon. The torque is unbelivable, so is the power. I had to settle for a Golf GTTDI instead of a GTI due to insurance and petrol costs, but this chip has just made it better than any GTI. My so called 140PS Golf is now one not to be messed with. Thanks Chip Express!

  • Danny from Ballymoney with a Suzuki Vitara 1.9 DDiS 129 said:

    I ordered a tuning unit last night and received it this morning at 10am. I have fitted it and the results are as you specified. The Vitara 1.9 DDiS runs beautifully and the poor torque at low revs has gone making the vehicle a pleasure to drive. Thank you very much for a great service and a brilliant product. It really does work!

  • Graeme from Galsgow with a Jaguar X-Type 2.2D 155 said:

    I fitted the Chip Express unit a few weeks ago, and have just had the car on an 800 mile round trip, Glasgow-Cardiff. Genuine 50mpg! Ran beautifully, with noticeably better acceleration, overtaking at 70 in 6th gear effortless, due to immense torque. I'm delighted. Thanks for a great product.

  • Eden from Auckland NZ with a Mercedes X164 GL350 CDI 224 Blue Efficiency said:

    I can not believe the difference, I was going to get rid off my new 2010 Benz GL, once a slug... now its a weapon, its unreal!! I also have a new BMW M3 but now my Benz is my favorite toy, cheers!

  • Derrick from Pontypridd with a Alfa Romeo GT 1.9 JTDm 150 said:

    The more I drive my Alfa the more I am pleased with your product. I recently drove to Newcastle, a round trip of over 700 miles. On my return I had achieved an average of 58.4 MPG. Fantastic! Thank you once again.

  • David from Chelmsford with a VW Golf MK5 2.0 TDI 140 said:

    WOW what a change, it feels like a different car... it now feels like I'm driving a GTi. Brilliant, brilliant, brilliant. I have not got a clue about engines but with your instructions it was easy! Thanks very much!

  • John from Frekhaug, Norway with a Honda CR-V 2.2 CTDi 140 said:

    I have installed the chip unit during the weekend and I am very happy with the results. The car is now much smoother to drive and has better pulling power ... I noticed this while driving the 55 kilometres to work this morning. I am normally using around 6.7ltrs/100 kilometres but today I was registering around 5.6ltrs/100 kilometres. The indicator on this car is pretty accurate as I often check this manually, which is very easy for me as I am driving the same distance each day. The new chip unit also seems to have solved two little niggles that I have had about this car. One was that it had a small flat spot/ hesitation around 1700rpm, which has now been cured. The other was that when coming into a roundabout I often had to drop down to second gear because the motor did not have the extra torque needed to go around in third, which is more often than not the more appropriate gear. Now I can comfortably go around in third gear and still have the ability to accelerate out again if required. I have already started to spread the word about this excellent product to all my friends and many colleagues!

  • Ryan from Cape Town, South Africa with a Audi A3 2.0 140 said:

    WOW what a difference! The first thing I noticed was that the revs in 1st gear where much higher and free flowing and then in all the others too. I could only drive in traffic yesterday, but still felt a huge difference with the car wanting to take off - easy tiger! There is a much smoother transition between the gears and much less turbo lag. Today I was on the open road, and WOW again. Great product!

  • Peter from Perth, Australia with a Jeep Commander 3.0 CRD 218 said:

    Please let me tell you how fantastic your Chip Express unit is, out of the box it provided a noticeable improvement in performance and a minimum 10% fuel consumption saving on my Jeep Commander 3.0CRD. The engine has now done 10,000km!

    I received my tuning box last week and am very happy with the ease of installation and the overall increase in performance!

  • Ryan from Pearl City, Hawaii with a Volvo Penta D3 190 said:

    My boat is a Grady White Gulfstream 205 (with twin D3 engines). With your chip’s and Stainless F7 propellers on I was able to reach 3800rpm at wide open throttle. My goal is to run my F8 props and hopefully reach 4000rpm. But as it sits now, the biggest and most impressive gain since fitting the chips was in full range acceleration. From idle and pushing water, to powered up and jumping up on plane was phenomenal. I started to apply power from just off idle (about 6 kts) right at the harbour mouth and by the time I cleared the wall and was out of the no wake zone, the boat had already jumped up on plane (without the stern drive tucked under) and was nearing 15 kts. This is within a distance of maybe 60 feet! Once up on plane the engine took off running and ran up to my half throttle setting instantly, I trimmed it out a bit and floored it, the engine rocketed up to 3600rpm then with trim and a little time it worked its way up to 3800rpm. I estimate about 37.5 knots. This is with a boat weight of roughly 4500lbs plus three adult men on board, fully rigged for open water fishing, and nearly 250lbs of ice on board! The best part is that at my normal “hunting” trolling speed of 8 knots or so, my consumption dropped nearly .5 gallons per hour, and down at the Tuna speed of 5.5 – 6 knots I was only burning .75 gph. And to top off the fun, we landed a 20lb Ono (Wahoo) without even knowing we had a strike! I just happened to look back and see the out rigger knocked down and the rod bent just a hair. Who knows how long we had been dragging him! Anyway, thanks again for your help, I love the chip, and can’t wait to turn the power up! I use the boat for wake boarding as well, so this will be a great improvement for pulling the person being towed up!
