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 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.

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.

Racehip+ DTS Black works great Racehip+ DTS Black works great! It was easy to install once I knew where my boost pressure sensors were located. Very easy to operate and very noticeable difference in performance increases across the low, mid, and high ranges.
