Feedback From Our BMW X3 Customers

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.
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!
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!

What others are saying...

“Your customer service, speed at which you deal with questions and chip (most importantly) are second to none. This is the 3rd variation of the chip that I have run, not only do I see the fuel savings made each and every time I fill up but I also feel the changes in the increased performance too. Far too often people only feel the need to leave negative feedback on a product, it's very rare that people take the time to leave positive comments however on this occasion I feel compelled to do so. A brilliant product and one that I highly recommend should you want to make the most of your cars potential performance and make a fuel saving to add into the bargain. What's not to like?! It's been a pleasure dealing with the team at Chip Express, I just wish everyone I dealt with in life was this professional! Thank you.”

“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 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!”

“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!!!”

“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!”

“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!”
