Like a race horse The ordering process was easy, the delivery was incredibly fast (Germany to Canada in 3 days), the install went without a hitch (I asked a mechanic to install), and the result is fabulous. An increase in HP from 333 to about 400 ! Wow. There were 2 glitches. 1. I had a tough time determining which boost pressure sensors were installed on my Audi S4 because I couldn't remove a sensor for inspection, I had to get help with that. 2. After the install was completed, the instructions weren't clear (to me) on the mapping progression. After tech support from Germany I learned that mapping 7 (the highest level) is where you want to be if performance is acceptable at that level. So my 2011 6 cylinder S4 with 170,000 km has acceleration like a race horse, and fuel economy as actually improved! Thanks to the Racechip guys. I'm having fun all over again.

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

Racechip 2020 Veloster Turbo DCT experience... I purchased the Racechip S for my 2020 Veloster Turbo DCT for an improvement in performance and driveability. It lived up to ALL my expectations....easy to install with very good instructions. After two days of driving, my car became a completely different animal. Boost came on much sooner, acceleration gains were incredible. Overall, I am VERY pleased with my Race Chip Experience. Buy one, you will NOT be disappointed, despite some of the NEGATIVE posts on Youtube. Don't believe the "naysayers" !!
