“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”

“Very impressive, even though it was short run after installation. Simple install, no warranty issue, this much of performance? Definitely the right choice !”

“Now it feels like real Cooper S. Couldn’t believe this small engine could be changed this much”

“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.”

“Love Swisschip. Can’t even imagine driving without it now. I was on 6-0 before now I am on 8-0 setting. Its been 2 weeks with 8-0 setting without any issues, I guess it is fine?”

“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.”

“Always think 2.0L engine is damn small. Now swisschip makes me feel i have bigger engine. Say 2.5L I am on 6-6 setting from initial 5-0. I am thinking of going 7-6″

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