RaceChip ChiptuningReviews of racechip.us

Great Product. The instructions that came with the unit were totally inadequate for my car's install. But I simply emailed RaceChip with my car info and they emailed me instructions and pictures of the exact model of my car's engine bay and install instructions.

Fantastic product and first rate customer service. Can't believe how fast it got here and the product itself exceeded expectations.

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.

I’m very satisfied, I installed this on my 2021 GLE AMG53 and you can really feel the torque and the rpms climb much faster!! Makes the car allot funner to drive.

Out of the box, this chip works. It is default to setting 5 and after installation I took it out for a test drive and could immediately tell the difference in power and the spooling of the turbo. Setting 7(highest) I couldn't notice much of a difference maybe if I take it to a track or put it on a dyno but in regular driving it wasn't noticeable. I tried the lowest setting #1(highway driving) to see if I could save on fuel but that didn't do anything, I get higher MPGs by turning it off. So for them to state that you'll get 20% better fuel consumption straight across is misleading. Now daily driving in the #5 setting with the extra power did result in similar MPGs as stock. This is based on multiple drives from northern California to Southern California and my daily commute is from sea level across a mountain(1800ft.) and back down twice a day. I've been using the chip for over 4 months now and I feel pretty confident I've given it enough hours to post a fair review. '16 Lexus IS200T F Sport 40k + miles

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!

Great performance upgrade for my C43. Very noticeable hp gains throughout the power range. Cost benefit is well worth it. It was also super easy to install.

Definitely worth the money got both the the gts and XLR. The gts I gained 48 hp and 85 tq. The XLR is good for better throttle response. My only issue is it's great off the line but seems to lose some puff as you hit the mid range and top end. You don't get to modify your settings they have settings from 1 to 7 higher the number higher the intensity of the tune. No regrets though happy with it for what it is. This is a new car with a warranty definitely the way to go as it leaves no trace it was there once it is disconnected you don't get that with a flash tune to your factory ecu. The pros definitely outweigh the cons.
