Great results on my BMW Great results! My car definitely definitely is faster and received an HP boost as measured through time trials. I bought the GTS black racechip and mobile app for my US model 2016 BMW 228i. The instructions were easy to follow (I used a Youtube video) and the app linked easily and seamlessly to my racechip. The customer service was helpful although I am very disappointed the engine warranty only runs for cars with up to 48k miles but that is stated on the website.

Racehip+ DTS Black works great Racehip+ DTS Black works great! It was easy to install once I knew where my boost pressure sensors were located. Very easy to operate and very noticeable difference in performance increases across the low, mid, and high ranges.

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.

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.

Like a race horse The ordering process was easy, the delivery was incredibly fast (Germany to Canada in 3 days), the install went without a hitch (I asked a mechanic to install), and the result is fabulous. An increase in HP from 333 to about 400 ! Wow. There were 2 glitches. 1. I had a tough time determining which boost pressure sensors were installed on my Audi S4 because I couldn't remove a sensor for inspection, I had to get help with that. 2. After the install was completed, the instructions weren't clear (to me) on the mapping progression. After tech support from Germany I learned that mapping 7 (the highest level) is where you want to be if performance is acceptable at that level. So my 2011 6 cylinder S4 with 170,000 km has acceleration like a race horse, and fuel economy as actually improved! Thanks to the Racechip guys. I'm having fun all over again.
