Feedback From Our Audi TT Customers

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!
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!

What others are saying...

“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!”

“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

“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.”


Alan from Coventry

“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!”

“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!!!”

“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.”
