Feedback From Our Audi A4 Customers

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.
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
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!
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.
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.
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!!
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.

What others are saying...

“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!”

Ford Kuga MK2 2.0 TDCi 163

“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!!!”

Ian from Manchester

Audi A6 MK4 3.0 BiTDI 313

“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.”

“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!”

“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

“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.”
