Feedback From Our Audi A8 Customers

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!
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!
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.
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.

What others are saying...

“A good product and a good service deserves recognition: I fitted a CHIP Express unit to my Insignia. What an amazing bit of kit! My fuel economy and performance went way up and with the mileage I do was a Godsend! On a run to Aberdeen from Hull I returned an average of 62 MPG and I drive quite energetically! I've just taken up the trade in offer and saved a few quid on a new system. The Vauxhall has now gone with 125,000 trouble free miles and I have changed car to a Volvo S60 D3. I'm looking forward to fitting the Chip Express unit and reaping the rewards, thanks guys!”


Frazer from Skirlaugh

Vauxhall Insignia MK1 2.0 CDTI ecoFLEX 130

“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.”


Simon from Ketteringham

Citroen C6 2.7 HDi 204

“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

“I was a sceptic at first, then after reading the experiences others had been through I decided to give it a go. I bought a new 1.7 CRDI Sportage, not the 2ltr purely for better fuel figures. Whilst this engine pulls very well in standard form, and was returning 44-45mpg even during the first 500 miles I had to go down the CHIP Express route. Well, there is absolutely no point in forking out the extra 2 grand for the 2 litre model when you can get the 1.7 and spend much less to get 2 litre power figures. Excuse the cliché’s, but this car is transformed and by a big margin too. From what I can remember about my 2 litre test drive, my 1.7 now pulls better than the 2 litre version. The low-down grunt is remarkable and pulls like the proverbial train. Fitting took minutes and was effortless, the box was kept on factory settings, I feel there is no need to mess with it. Needless to say I am now a very happy boy and would without question take this route again. I would recommend this to any diesel Sportage owner. Many, many thanks for a remarkable product and a customer service that is rare in this country!”
