Well executed Grabbed base S for 2019 Civic 1.5T to smooth out low end throttle response. Arrived promptly, well packaged, easy install. Immediately addressed issue at default (3) setting. After a few weeks noticed small but consistent mileage improvement (6-8%); wasn't expecting that. Tried upper two settings; ultimately settled on 4 which offers some nice scoot in the RPM range I prefer. Would purchase again without hesitation.

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.

Veloster turbo RaceChip I bought the race chip for my veloster turbo and 100% love it!! Shipping time was fantastic, with it coming from Germany to PA in just a few days. The packing was fantastic and the install was super easy. Instructions were clear and easy to follow, they even include a little guide booklet with tips on how to remove differnt kinds of connectors. Very pleased with this product.

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.

great hardware and outstanding customer service First I want to say that this chip really works, it makes my car more responsive and eager. After about 4 months I had an issue with the Bluetooth so RaceChip sent me a return label so I could send it back to them to get it checked out. 5 days later I had a new chip in my hands, and that included shipping from the US to Germany and back! So not only it’s a great chip, they also stand behind their product and take care of any question or problem you might encounter promptly. Truly a 5star company and product.
