Feedback From Our BMW X3 Customers

Justin from Congleton with a BMW X3 E83 3.0sd 286 said: First class device with the support to back it up. I have a CHIP Express box fitted to my BMW X3 3.0sd 286PS. The tuning box makes the cars power delivery more linear and irons out the flat spots. There support service is excellent and will bend over backwards to help you out. I highly recommend CHIP Express for your tuning box needs.
Yosa from Thailand with a BMW X3 F25 xDrive 20d 184 said: I have received your product with thanks, it only took just 5 minutes to install on my BMW X3 2.0 diesel F25! My first impression is the much improved acceleration. Very happy indeed and thank you for the quick delivery!
Alan from Telford with a BMW X3 F25 xDrive 20d 184 said: I just wanted to pass on a little (good) feedback. I fitted the unit as soon as it arrived, and after a little hiccup (100% my fault) it’s working perfectly. My onboard commuter was giving me a reading of 44mpg before the unit was fitted. Now 200 miles later I’m getting 55mpg. A fantastic result that I hope to improve upon as I bought the unit for better economy. Thanks again for your help and a great product!
Nick from Croydon with a BMW X3 F25 18d 143 said: Only just got around to commending you on the supplied chip for my BMW x3 143PS. Interesting that BMW have upped the power on the facelifted X3 to 150PS but the chipped version you have supplied is more powerful and responsive - it just can't wait to get into upper gears! MPG average is already creeping up. I also find the engine quieter, more driveable and 'fluid' in all road conditions - looking for an excuse for a long run! Well done.

“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.”

“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!”

“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!”

“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!!!”

“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.”

“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.”
