I Have had the GTS Black and XLR on my ‘19 Audi S5 Sportback for about 1.5 years now. Overall the performance in Highest setting R+ mode is noticeably peppier, but it’s not an extreme difference like you would see in a full ECU Flash. Still, RaceChip is worth every penny as you get mild performance increase with no worries of voided warranty or a damaged motor. The App has a few MAJOR MISSES that would make it 5 stars IMHO: APPLE CAR PLAY integration… this is a no brainer!!! Would make life so much easier switching modes without fumbling for or swiping through your phone. Please integrate CAR play 🙏🏻 XLR CUSTOMIZATION - when pairing the RaceChip with an XLR throttle controller, it would be a great feature to be able to setup the XLR so you can cycle through your preset modes (Race, Sport, Economy) on the physical device and it changes your RaceChip setting as well. Being able to quickly change modes on the fly (without getting iphone, opening app, connecting, etc) is the biggest miss. Why not make the XLR able to change the modes of both with the physical buttons?? Also thought there would be updates to the “tune” occasionally, as RaceChip sells more units and collects more data. Unfortunately I haven’t seen any tune updates at all. I guess it’s as good as it gets 🤷🏻‍♂️

I have a race chip RS on a 2022 BMW440. My phone is an iPhone 14 pro, iOS is 16.3..I can change which mode my Race Chip is in, but I only have level 1 and 2 on eco, sport is in level 3 and can’t not be adjusted and Race is only levels 4,5,6. Should each mode have 6 tuning levels or is this the way that the Race Chip RS has 6 fine tuning levels..thanks for any help..

Just got a race chip and love the difference of performance! You should make a Apple Car Play app so instead of having to reach for the phone to change modes, it can be done using the car itself. Also a 3D Touch or whatever is called would be nice for quick access to change the modes instead of opening app. Or even a widget option. Would be nice if it was able to show some stats like a dyno does but not sure if that’s possible.

I got the racechip for my 2017 Jetta. After reaching out to the incredibly helpful support team at racechip I was able to work out a few silly mistakes causing errors. The performance increase is noticeable and being able to switch between modes is fantastic as well! I have never left a review before, but seeing how this product has no reviews and how great I was treated, I thought I’d leave one.
