Matthew from Pinner with a BMW 3 Series E90 330d 245 said:A very very good product. A noticeable difference in economy (roughly 5-10%) and you can 100% feel the additional performance. Makes a huge difference in the lower rev range reducing turbo lag. It makes driving swiftly effortless, with the added benefit of improved economy. I have had my car from new in 2011 and installed the unit almost as soon as I'd purchased it. I have had multiple services at BMW service centres over the last 5 years and removed the unit beforehand (just in case) and they have never noticed. I'm not sure if they have an issue with these kits or not, but my experience with BMW is that they'll do anything to get out of a warranty repair, so just to be on the safe side. CHIP Express on the otherhand have given absolutely amazing customer service and support. This is hugely appreciated and gives me further confidence in the product and company, I will never run a turbo diesel without one again!
Stuart from Newcastle with a BMW 5 Series 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.
Kani from Istambul, Turkey with a BMW X1 E84 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.
Alf from Cheltenham with a BMW X6 E71 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.
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.
John from Ashton Keynes with a BMW 3 Series 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.
Robert from Flynn, Australia with a BMW X5 E53 3.0d 204 said:Makes a great difference to take off, much smoother and more responsive. Bang for buck this is great!
Simon from Hamiltonsbawn with a BMW 5 Series 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.
Alan from Whiston with a BMW 5 Series 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!
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!
Tim from Morthoe with a BMW 5 Series 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!
Mark from Godalming with a BMW 3 Series 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!
Yosa from Thailand with a BMW X3 F25 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!
Malcolm from Bournemouth with a BMW 5 Series E60 520d 177 said: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!
John from Goole with a BMW 3 Series 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.
Robin from South Yorkshire with a BMW X6 E71 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.
James from Annery with a BMW 3 Series 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!
Mark from Godalming with a BMW 3 Series 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.
David from Darlington with a BMW 3 Series 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.
Ulrik from Auckland, New Zealand with a BMW 3 Series E90 335d 286 said:Been absolutely loving your product in my BMW 335d for 80,000km. Thanks again for giving me 4 years of smiles from ear to ear and more horsepower than one knows what to do with... most of the time!
John from Epsom with a BMW X5 E53 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.
Dr Mahmoud from Waterford with a BMW 3 Series 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!
David from Duns with a BMW 5 Series 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!
Matt from Filderstadt, Germany with a BMW 3 Series 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.
Steven from Melvourne, Australia with a BMW 5 Series 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!
Mark from Thame with a BMW X5 E70 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!
Rex from Devizes with a BMW X5 F15 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.
Mark from Sittingbourne with a BMW 3 Series F30 320d 184 said:After much thought and even more research I bought my first CHIP Express tuning system about 6 years ago for a new BMW X3. It was straightforward to fit and made a significant improvement to swift progress (!), smoothness and (even more impressively) economy. When I changed to an Audi I contacted CHIP Express who exchanged (professionally, quickly and at a great price) my existing unit for a new one. Same brilliant results. I'm about to return to BMW (a 2015 3-Series 320d xDrive) and have done the same again. Brilliant Company offering a product that really delivers on all that it promises. P.S. Product brilliance notwithstanding - the customer service is absolutely first class.
Dave from Hainaut, Canada with a BMW 5 Series 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!
Keith from Chepstow with a BMW X1 F48 25d 231 said:This is the second BMW in which this chip system has been fitted. In my BMW 1 Series 120d xDrive M-Sport I ended up on the top settings and the increase in performance, acceleration and fuel economy was quite stunning. Having had the chip retuned, it is now fitted to my BMW X1 25d xDrive M-Sport and after 5 days I have once again moved to the top position. The results are obvious, in acceleration, fuel economy and outright performance. I would recommend this "CHIP Express" upgrade chip to anyone AND by removing chip and attached connectors the car is returned to factory delivered state with NO evidence of chip installation. The exchange of correspondence has also been excellent. Great company, highly recommended.
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!
Hugh from Ashtead with a BMW 5 Series 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.
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 Sankt Gallen, Switzerland with a BMW 5 Series 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!
Rod from Ballymena, Ireland with a BMW 3 Series E92 320d 184 said: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.
Keith from Chepstow with a BMW 1 Series 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!
David from Westerham with a BMW 5 Series F10 / F11 520d 190 said:I have fitted the unit with no stress at all, I think I was over thinking it to be honest. Anyway, I cannot believe the difference in has made to my car. the is so much pull it is like a full engine transplant. Thank you very much.
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!
Nick from Croydon with a BMW X3 F25 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.
Colin from Kintore with a BMW X2 F39 18d 150 said:This is the second chip I have bought from yourselves with exceptional results. In the UK you can't buy an X2 190PS with the manual gearbox so had to settle for the 150PS motor, however with the chip fitted I now have the power and torque I wanted... GREAT!
Don from Auckland, New Zealand with a BMW 3 Series G20 / G21 320d 190 said:Greetings from NZ. Just a heads up that the new chip unit that you shipped was in my mail box this morning! Have now fitted it and once again WOW WOW WOW, and as I am now onto my 3rd CHIP Express, thought I was used to the additional power and smoothness, but it never ceases to amaze me!
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.
Stuart from Ayr with a BMW 6 Series 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.
Allan from Kilwinning with a BMW 3 Series F30 / F31 320d 190 said:I ordered my CHIP Express yesterday and it arrived first thing this morning. Great service. I was dubious about the fitting as I know absolutely nothing about car engines and seriously considered taking it to the local garage to ask them to fit it. But on reading the other reviews I thought I’d have a look under the bonnet to see if I could have a go. I have a new BMW 320d xDrive and on following the instructions sent with the chip it took me LESS THAN 10 minutes to fit it and secure it in the pouch in the engine bay with the Velcro cable ties. The car runs perfectly and the difference is noticeable immediately. It’s an automatic and I no longer get a jerky drive off, acceleration is also smoother and faster. I would recommend this to anyone thinking of upgrading their vehicle performance. If I can fit it anyone can! Thanks CHIP Express for a great product.
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!
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!
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.
Lee from Halifax with a BMW 1 Series 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.
Andrew from Thame with a BMW 3 Series 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.
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.
“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!”

“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!!!”

“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.”
Simon from Ketteringham
Citroen C6 2.7 HDi 204
“Be assured, this is NO gimmick. Arrived yesterday (less then 24 hours after the order was placed) and fitted today. The fitting was easy especially with the photos and instructions sent with the chip. The first thing I noticed was the responsiveness of the engine from a standing start, no more lag. I then went on a 30 minute drive both motorway and sideroads and my average fuel consumption went UP from 33.3mpg to 38.7mpg. My motorway speed varied from 60 to 85mph and the sideroads from zero to 40mph. I am so pleased with the whole result. This is worth every single penny paid. Thank you!”

“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.”

“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.”
