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.

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.

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!

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.

The GTS Black race chip is very good… The GTS Black race chip is very good and gives a real good boost to my Honda Civic Si _Copue 2018 . from aprox 205 hp to aprox 250 hp. I am using it together with a street version PRL air filter but as I read the chip is indicated for a stock engine without any modification, so from time to time the engine fails very rarely in the initial acceleration by absorbing too much air since as the PRL street air intake is installed it absorbs more air than original. When I changed to the PRL race version air intake, I couldn't use it anymore because the air intake is almost 50% + air so the race chip is no longer enough and you have to do a reprogramming with Hondata or KTuner . In any case, today this chip is excellent for those who do not want to change the standard of a car and increase a good amount of power and use the maximum possible power of your car as standard. I would like you to also prepare for normal trucks like the 2.4 L Mitsubishi Outlander that I have but apparently you focus on other types of engines, in fact, I have a RoadRace chip from the USA, specially designed by them for their race SUVs, for my 2017 Mitsubishi Outlander increasing the power by 12 to 15% is a good bit to improve the performance of the engine. Greetings and keep up the good work.
