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.

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.

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.

The chip is fabulous The chip is fabulous, it works. I've only had one problem and it was not with the chip, it was with the app and it was caused by me, since I changed my phone. Of course, the chip and the phone had to be paired again, as I am not an expert the pairing took me a couple of weeks, but with the help of Patric Richardson from the RaceChip Customer Service, I was able to solve it finally. I have no hesitation in recommending this German company.
