Great product! Lighting fast shipping, and it was going international. Straight forward instructions made the job fast. Once installed, wow, instant power difference. Makes spirited driving a blast, totally changed the experience. 2018 BMW X1, worth every penny in my opinion. I would recommend not using the “race” setting at full power all the time as I’m sure the stock components can’t handle it lol, but when you want to have some fun, the option is there.

great hardware and outstanding customer service First I want to say that this chip really works, it makes my car more responsive and eager. After about 4 months I had an issue with the Bluetooth so RaceChip sent me a return label so I could send it back to them to get it checked out. 5 days later I had a new chip in my hands, and that included shipping from the US to Germany and back! So not only it’s a great chip, they also stand behind their product and take care of any question or problem you might encounter promptly. Truly a 5star company and product.

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

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.

Really impressed with racechip from… Really impressed with racechip from shipping to packaging to installation all seamless and quick. Racechip has done exactly what they said it would do, and nothing less. Very happy over all with the product! This is by no means a full ecu tune, but it does exactly what it’s suppose and makes for a more enjoyable/fun ride.
