“I testdrive powerkit of 435i which is good. I got normal one tho, the price for the powerkit is too high. I chose swisschip that was what one of my pals did to his porsche. Now it is much better BMW powerkit. Overall ‘GOOD’ “

“After installation, I am able to feel actual differences with the car. Been using it for just 3 days it got so much better the first.. I am loving it. But i am being greedy so trying higher setting. I love to know what swisschip can do for mazda.”

“I was so unhappy with this lame ass car. Diesel Lag/slow acceleration stressed me out. Wished i got 35i engine. I never believed swisschip. But unexpected result. I feel like the performance increases 15-20% for sure. Guarantee this is the one that also suitable for other cars i have”

“Simple. If you have a problem with this thing you get refund. But me, I am satisfied with this thing. I can see big differences in power and stuff. Wonder how small chip like this can change whole car”

“No other shops could upgrade my car. Luckly found swisschip. I am so 100% sure this is the only thing that keeps my Panamera going well. I am glad they chiptuned my car. Now I got it. The result is more than i expected. Loving it, Thanks Swisschip.”

“Without swisschip I would absolutely get rid of my car. Swisschip actually helps transmission lag better. I definitely keep this car for another year it will save lotta money as well. Highly recommended.”

“I was always hoping my car has more power. One of my friends recommend swisschip. I am so happy with it. It is really good and working well. From the start to mid high speed all got better than before. I was not sure if it helps transmission better. I sense it does.”

“No one can do AMG before swisschip, I had no other choice. I know its greedy to tune my car, now everyday is like the first day I drove her ”

“Very good product. I went camping last week with family. My son also say it’s better performance now. Might get one for his golf too. Thank you swisschip guys.”
