Feedback From Our Audi A3 Customers

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.
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.
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.
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!

“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!!!”

Audi A6 MK4 3.0 BiTDI 313

“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!”

Edwin from Bridgend

Ford Kuga MK2 2.0 TDCi 163

“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

“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.”

“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!”

Land Rover Freelander (2) SD4 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.”
