The chip is fabulous The chip is fabulous, it works. I've only had one problem and it was not with the chip, it was with the app and it was caused by me, since I changed my phone. Of course, the chip and the phone had to be paired again, as I am not an expert the pairing took me a couple of weeks, but with the help of Patric Richardson from the RaceChip Customer Service, I was able to solve it finally. I have no hesitation in recommending this German company.

Race chip did delivered Race chip did delivered! A phenomenal device with multiple settings all enhancing my vehicles performance. Directly after install they were noticeable gains in both power and torque to my Volkswagen Jetta 1.4 L T.

Great Product and customer service Great Product. The instructions that came with the unit were totally inadequate for my car's install. But I simply emailed RaceChip with my car info and they emailed me instructions and pictures of the exact model of my car's engine bay and install instructions.

Great results on my BMW Great results! My car definitely definitely is faster and received an HP boost as measured through time trials. I bought the GTS black racechip and mobile app for my US model 2016 BMW 228i. The instructions were easy to follow (I used a Youtube video) and the app linked easily and seamlessly to my racechip. The customer service was helpful although I am very disappointed the engine warranty only runs for cars with up to 48k miles but that is stated on the website.

Improvements across the board! I can honestly say that I got both an increase in power AND improved mileage so far! The installation was pretty simple but, finding a spot to mount the unit (away from heat) is tough in a small car. There is still periodic disconnection with my phone app but, all in all my experience has been positive! I'd do it again!
