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.

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.

Thanks for saving my AMG CLA-45 Mercedes! I have an AMG CLA-45 Mercedes that had horrible turbo lag (I live in California, the worst state for cars in the USA due to strict pollution laws). I purchased the middle RaceChip device with BlueTooth and it completely transformed this from a frustrating car with horrible turbo lag to one of the most fun cars I have ever owned. The selectable tuning is awesome, I have tried several settings over the last few months and they all work great. I highly recommend RaceChip, this product is everything they promised.

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! Lighting fast shipping, and it was going international. Straight forward instructions made the job fast. Once installed, wow, instant power difference. Makes spirited driving a blast, totally changed the experience. 2018 BMW X1, worth every penny in my opinion. I would recommend not using the “race” setting at full power all the time as I’m sure the stock components can’t handle it lol, but when you want to have some fun, the option is there.
