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
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.
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!
Stephen from Essex with a Audi TT MK2 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!
Peter from Richmond with a Audi A8 MK2 3.0 TDI 233 said:It does exactly what it says on the tin! Cannot fault the extra performance and extra MPG. After 9 years would highly recommend and not hesitate to purchase again. Paid for itself in no time at all. One very happy user.
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!!!
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.
Bill from Silsden with a Audi A5 MK2 3.0 TDI 218 said:Unit delivered this morning, excellent service. Initial impressions - very well made and presented with great packaging. Fitting took about 5 mins. Having had it out on the road, I have to say I am impressed, power delivery is very smooth and progressive, and what was already the smoothest quietest diesel I ever had is now even smoother and exceptionally quiet even under hard acceleration. So all good. Cheers, Bill.
Mark from Newburgh with a Audi A8 MK2 3.0 TDI 233 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.
Nigel from Barrow-in-Furness with a Audi A7 MK1 3.0 BiTDI 320 said:Thank you, my car is now how I feel it should have been when it left the factory! I own a 2015 Audi A7 3.0 TDI Bi Turbo, after spending 5 minutes fitting your tuning chip my car has lost the annoying bottom end flat spot and the elastic throttle response in all modes other than sport. I have had so much fun on my first drive since fitting your unit I cannot comment on the MPG savings but what I can say is the instant fuel MPG meter looks to spend more time at the top end, so I do believe driven like for like your claims for improve economy to be true. Without doubt the best MONEY I have ever spent. If you want to use my message as a testimonial to encourage other to buy please feel free.
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.
Anthony from Umina Beach, Australia with a Audi A7 MK1 3.0 BiTDI 313 said:Having previously Chip-Expressed my Audi 3.0 TDI Allroad, I was keen to do the same to my recently purchased A7 BiTurbo. The A7 BiTurbo is fast in itself, but it’s moved to a whole new level with the CEx chip. I sold a 5.7L AMG E55 to buy this A7, and it’s now amazing how close the A7 is to the E55 in terms of rolling performance…....with the save-the-plant benefit of 1/2 to 1/3 of the fuel usage. And I’m probably getting 10% better fuel performance from the A7 after after fitment. What’s not to love!
Bill from Silsden with a Audi A5 MK2 3.0 TDI 218 said:Well I have to say I am really surprised, I was a bit skeptical! I have had remaps a couple of times and plug in tuning boxes several times, and whilst I know they work, I was taking large pinches of salt as I was reading your website, as every other chip I have had showed great MPG improvements in fuel consumption, which was always debunked by doing tank full to tank full calculations. Now two full tank to tank calcs later I surrender! I don’t know how you did it but it appears you have. Pre chip I was averaging 42-44 MPG per tank full, with distance covered being between 475 and 490 miles. The last 2 tank fills since fitting have been 517 with an mpg of 46.34, and 510 with an mpg of 47.23. In addition the turbo lag has virtually gone and what was an already very swift and flexible engine is now improved enormously, so I have to say thank you!
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.
Dejan from Ivanic Grad, Croatia with a Audi A6 3.0 BITDI 313 said:I have had this chip installed for almost 2 years on my Audi A6 (C7) 3.0L BITDI and have covered approx 80 000km since. The additional power has turned this into a top purchase! I have since bought a chip for my Vivaro 2.0 CDTI van, this was mainly because I put 17" wheels with 225/55 tires, so van was dead on the road without the additional power of the chip. Thanks from a more then happy customer!
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!
Roger from Cippenham with a Audi Q5 MK1 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!
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!
William from Limassol, Cyprus with a Audi SQ5 MK1 3.0 TDI 313 said:I had considered fitting a chip for some time but had my doubts, seeing the reviews on your web page changed my mind and now I share my experience. The chip was promptly delivered and installation was done in the 5 minutes as stated. First thing to notice was a reduction in engine noise. Test drive immediately showed improvement in torque and power which is significant considering that the SQ5 is already a powerful car. Driving pleasure is improved. Economy, whilst this wasn't a priority on a regular run on the highway under similar conditions driving for one hour economy improved from 7.7 Lts/100 Km to 6.8 Lts/100 Km. Under urban conditions the improvement is about 1.2 Lts/100 Km. CHIP Express delivered what it was said it would and now some of my colleagues are looking at this option. Thanks, William.
David from Bridge Of Weir with a Audi Q5 MK1 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!
Brendan from Hertfordshire with a Audi Q5 MK1 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.
Colm from Waterford, Ireland with a Audi A8 MK3 4.2 TDI 350 said:Just fitted to my A8 4.2 TDI... WOW!!! I am so pleased with the new performance! With regard to economy, I used to have a 500 mile range but now with chip tuning I have a 630 mile range!
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.
Ryan from Cape Town, South Africa with a Audi A3 MK2 2.0 TDI 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!
Clive from Tatworth with a Audi TT MK3 2.0 TDI 184 said:The chip instantly transformed the response of the engine. The massive low down flat spot has now gone and power is available at all throttle openings. The engine is far more powerful throughout the rev range. The only let down is the TT's gearing which in 1st and 2nd seems to low for such a car. Once in 3rd she really pulls like a train. Improved economy too, on a run I can get over 60mpg, about town and normal driving I get high 50’s. Prior to fitment the best I got was low 50’s. Customer service is exemplary. I recommend the unit to all of my friends with diesel powered cars and vans. Best accessory you can buy for the money!
Steve from Houghton-le-Spring with a Audi Q7 MK1 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.
David from Basingstoke with a Audi Q5 MK1 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.
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.
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!
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.
Paul from Newcastle Upon Tyne with a Audi Q5 MK1 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!
Steven from Shifnal with a Audi A6 MK4 2.0 TDI 190 said:Holy Dooley... I'm impressed! First off, I ordered the item at 3pm on a Monday and had a knock from the postman at 11am the following day, that's only 20 hours from order to having it in my hand. Secondly it took me less than 4 minutes to fit the device to my new A6 Avant 2.0 TDI Ultra. Thirdly I have just cracked 53.1 MPG on a short (2 junction) motorway run (which is up from a previous best of 47.2 after a long motorway stint), to see what the device was like and ensure there were no warning lights etc or general issues with running it. So far nothing has indicated that the engine is not happy running this device. Fourthly the performance has improved considerably and that's running on the default settings. All I can say is that for a first impression on service and performance CHIP Express has done exactly what it says on the tin, which in this day and age I find quite rare. I am really really impressed with both product and service... and I've not said that for sometime.
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!!
Mark from Harpenden with a Audi A7 MK1 3.0 TDI 204 said:The chip in the A7 has performed wonders. I just wanted to say what an amazing difference it has made! Fantastic product and A1 customer service. Very happy customer!
Grant from Flat Bush, New Zealand with a Audi Q7 MK1 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!
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.
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!
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.
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.
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!
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!
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.
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!
Benjamin from Gosport with a Audi A8 MK2 3.0 TDI 233 said:I felt after a few years of having boxes from you I would drop you a line to say how good your product has been. I have had two vehicles with CHIP Express tuning boxes. The box from my 2008 A6 2.7 TDI 180 being exchanged and programmed for my 2008 A8. The service was superb and very quick. These Multitronic Audi gearboxes are super smooth anyway, but they became smooth like a payne of glass with the box fitted, especially the A8, which became barely noticeable when changing gear. The power increase was awesome and the fuel economy went up by around 5 mpg which in an A8 is welcome! Overall both of my cars have been even more joyous to drive when fitted with these boxes. I have also recommended you to a few people who bought boxes and have been equally as pleased!
Mark from Victoria, Australia with a Audi Q7 MK1 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!
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 noticeable boost to the already lively diesel - the Quattro still gripped with ease and gave a really impressive acceleration 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.
Randolph from London with a Audi Q5 MK1 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.
“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!!!”

“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!”

“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.”
James from Callington
Land Rover Discovery (3) 2.7 TDV6 190
“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.”

“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

“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!”
