Having read alot of negative comments about tuning boxes I was very sceptical about trying one. I have had four previous turbo vehicles re-mapped and was always very impressed with the results in terms of power and economy gains. Ill be honest in that the car certainly did not need any more power than it already had. Now when I put it in sport mode it takes off like a bat out of hell! Thank you!Īndrew from Thame with a BMW 3 Series E90 320d 177 said: I have a 58 reg BMW 320D AUTO and I have recently fitted one of your Chip Express tuning systems to it. The way the car drives has completely changed as the power range, it used to be mostly between 2000 to 3000 revs, and it now drives more like petrol cars I've had with revs going all the way to 5000 without straining. I've been on two out of town trips since the weekend and not only noticed the extra torque (car will accelerate from 40mph in sixth gear) but my MPG has gone from 52 to 61. I took it for an initial drive round the block on and checked for engine lights or black smoke, but things were good. The photo guidance is really easy to follow and everything just clicked in. I was a bit nervous but ordered the chip on Friday and was delivered 9am Saturday morning. It got me thinking and my search started for a reputable product to fit to my one year old car. The dealer informed me the engine is the same in both models but they're just chipped differently. The car was ok to drive and lively when I needed it, but I wanted the power of the 320d.

Anyone thinking of improving their MPG and power output in these harsh economic times would be well advised to consider CHIP Express before many other alternatives. First class product, first class service. I cannot recommend your company too highly.
I can report that over the last week I am starting to get an increased MPG. From contacting you and you returning the new chip took 5 days, and within 5 minutes this was installed. I have been so satisfied with the service provided that, when I changed again to a BMW 530d, my first port of call was to yourselves and you have not let me down. When I changed cars to an Audi A8 3.0 TDI, you reprogrammed the old chip for very sensible money and once again improved power output and my MPG. First on an Audi A6 2.7 TDI, which increased my MPG from 37 to 40 together with a marked improvement in power delivery.
