“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 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’ “

“Realised after to peel clear plastic off the sticker. Now my Great wall has power like my Colorado now, wicked Cheers”

“Thank you very much guys. I beat pure e92 M3 on both drag and roll racing ! couldn’t expect this much result, amazing !”

“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.”

“It’s been around 1200km now with swisschip, I absolutely love it. It gets rid of the dead spot from take off. I will try next notch soon and let you know guys. Cheers”

“I think it is a perfect add on my car. No more lag and better acceleration. I knew that I was right when my wife talked about it with doubts. Thanks to swisschip. Hope i use it for long time without any problems.”

“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”

“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”
