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

Great customer service/ great product for VW/ Audi! Great customer service. A few things came up, but they shipped replacements quick and update over the app settings very fast. Highly recommended!! Buying another race chip product soon

Own a 2015 Audi SQ5 Own a 2015 Audi SQ5. Great web-site that provides all the right information and several options at a good price. Purchased the RS w/app. Received pretty quick and install was simple and instructions covered troubleshooting. Just tested on a Dyno after having it a few weeks and HP increased 38-48! Significant difference w/o spending thousands! Great product that’s true to its claims. Thanks guys!

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.

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!
