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.

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.

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.

Amazing results!! Amazing results!!! 2017 Cayenne Turbo (500hp) Installed both the RACECHIP and throttle controller. Big difference. Better than I expected! The car is a lot different. Now 580hp but actually feels twice as fast and twice as responsive... Much more fun to drive! Thanks! Charles, CorpAuto
