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!

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.

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.

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.
