Feedback from our BMW 3 Series customers:

  • Andrew from Thame with a BMW 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. Ill be honest in that the car certainly did not need any more power than it already had. I have had four previous turbo vehicles re-mapped and was always very impressed with the results in terms of power and economy gains. Having read alot of negative comments about tuning boxes I was very sceptical about trying one. I decided to take the plunge though, for the fact that with this system I can remove it (in 5 minutes!!!) for when the car goes to the dealer as it is still under warranty. I can honestly say that this system is equally as good as a remap, but with the added bonus of being able to remove and fit in minutes. Also I now find that the Auto box shifts up gears at lower revs and holds gears under strain much easier. And WOW it really moves now!! Its easy to forget your only driving a 2.0 litre diesel. All in all I am very impressed and would recommend you to my friends and family. Fantastic product!! Well done.

  • Dr Mahmoud from Waterford with a BMW E90 320d 177 said:

    Many thanks for your prompt delivery (ordered Friday, received Monday in the Republic of Ireland). May I suggest that you change the name to TORQUE Express! I already had a tuning box which produced a max of 215PS for my E90 320d BMW (177PS). Whilst decent enough, there was considerable piston slap under hard acceleration. The CHIP Express tuning system provided a much quieter and smoother power and torque delivery without fuss! The system is intelligent in the way it soon adapts to your driving style and the way the vehicle is being driven so you do not get the sudden jolt you might get with other boxes under hard acceleration. I am really impressed with the overall performance of my 3-series and I think you set the benchmark for diesel tuning systems. The CHIP Express system is indeed a template for diesel performance enthusiasts. It really is that good. I rest my case!

  • Terry from Northampton with a BMW 3 Series F30 318d 143 said:

    I found the 318d was cheaper than the 320d with better spec thrown in. The car was ok to drive and lively when I needed it, but I wanted the power of the 320d. The dealer informed me the engine is the same in both models but they're just chipped differently. It got me thinking and my search started for a reputable product to fit to my one year old car. I was a bit nervous but ordered the chip on Friday and was delivered 9am Saturday morning. The photo guidance is really easy to follow and everything just clicked in. I took it for an initial drive round the block on and checked for engine lights or black smoke, but things were good. 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. 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. Now when I put it in sport mode it takes off like a bat out of hell! Thank you!

  • Rod from Los Angeles, USA with a BMW 3 Series E90 335d 269 said:

    I ordered the chip thinking that the claims made in prior testimonials could not live up to the hype. Boy, was I wrong! This chip delivers just as advertised, I could not be more pleased. I am so pleased, that I am ordering another for my 2012 BMW X5 35d and telling anyone that will listen to get their very own.

  • Matt from Filderstadt, Germany with a BMW E90 335d 286 said:

    I bought the CHIP Express diesel tuner for my BMW 335d Touring 5 months ago. The car performs flawlessly on the Autobahn here in Germany. The tires now break traction under hard acceleration if provoked, its great! I will always recommend your product. Tschüß.

  • Mark from Godalming with a BMW E90 318d 143 said:

    Just wanted to write in to thank you for a fantastic product which increased the drivability, power and efficiency of my new BMW 3 series and gives me the same power as the next model up! A great 'plug and play' product which can be fitted and removed in a couple of minutes. I was concerned that it wasn't going to work but I shouldn't have worried. Couldn't recommend your product enough as well as your excellent customer service.

  • James from Annery with a BMW E91 330d 231 said:

    Great product! Fitted first chip to my BMW 320d made it so better to drive no with no flat spots plus better on fuel by about 5mpg. Now fitted second chip to my BMW 330d which pulls like a train which so much more torque, very happy with service, a top company!

  • Mark from Godalming with a BMW F30 320d 184 said:

    Had a CHIP Express chip in my BMW E90 318d 143PS for 18 months and been absolutely delighted with it. I returned the chip for an upgrade when I changed my car to a BMW F30 320D xDrive M Sport. The upgrade was done in super quick time and the installation quick and painless as usual. After about 2000 miles of driving in all conditions I'm pleased to say that the chip works even better than before! My MPG has gone up by about 12-15% and I can push about 600 miles out of a tank (up from just over 500 before the upgrade) and the difference in the acceleration in all gears (including Sport mode) is fantastic. It's a completely different car, which is now more efficient and more powerful - feeling basically like the next model up in the range! Many thanks for such a fantastic serivice and product!

  • Scott from Meriden, USA with a BMW 3 Series F30 328d US Spec 183 said:

    I just wanted to let you know how impressed I am with my chip tune. Installation was as easy as it gets and BAMMM, huge difference. Its like a whole new car. I actually bought Dyno-Scan from Auterra which runs on my Galaxy S4 through Bluetooth connected to the OBD II port to measure the HP/TQ and the results were 228BHP and 366 LB-Ft TQ. No one should hesitate to buy this tune for their cars, they won't regret it.

  • Olli from Surrey, Canada with a BMW 3 Series F30 328d US Spec 183 said:

    I have installed the Chip Express, it is terrific! Installed it in 5 minutes... performance is great... the engine feels and sounds totally unstressed... best increase in performance for the money, period! You can put me down as a very satisfied customer... p.s. if you want to add me to the reviews, feel free!

  • Koutsoudis from London with a BMW 3 Series E90 320d 163 said:

    A Very easy installation. Feels like I am driving another car. Great job guys and just one more word... PROFESSIONALS!

  • John from Goole with a BMW F30 330d 258 said:

    I originally fitted my chip to my 325d BMW, after sending it back for re-programming it was then fitted to my BMW 330d, I found the power and fuel economy to be exceptional. I am now changing to a VW Amarok 2.0 BiTDI due to work and I have just sent it back for re-programming again. I have found the service Chip Express provide to be first class in the years I have been using their chip and have just recommended them to a work colleague, who is seriously considering fitting one to his car.

  • Mike from Siilinjärvi, Finland with a BMW 3 Series E90 320d 163 said:

    I thought about this purchase for about a year. Since fitment I'm so happy, the car is totally different in a REALLY positive way, my 4 cylinder engine now has 6-cylinder torque output, as a result the throttle response is immediate and my consumption has also dropped by 0,9l/100km, now that's impressive! Keep up the good work guys.

  • David from Darlington with a BMW E90 320d 177 said:

    Wow, I just cannot believe the difference. It is like driving the 3lt diesel with 50mpg+. I don't know how you have managed it and it shows that for whatever reason BMW are not getting the best out this engine in std tune. Thanks very much and have recommended to all my diesel driving friends.

  • John from Ashton Keynes with a BMW E90 335d 286 said:

    Just a quick note to say many thanks for the prompt delivery. I fitted the device this afternoon and am very pleased indeed with the results - as you said, the throttle response is much more linear and consequently the car is significantly easier to drive. My wife has just been out for a drive and is also delighted with the results, so many thanks.

  • Rod from Ballymena, Ireland with a BMW 3 Series E92 320d 184 said:

    Got chipped and so far so good. Torque is noticeably up, much more low rev pull. Economy is also up by 2-3 mpg. Auto box is now even smoother for gear changes. Hope the MPG improves even further as my driving style gets used to the less heavy acceleration now required since chipping.
