“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’ “

“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”

“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”

“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?”

“I was about to get ABT powerkit which is very pricy. So what i went with was swisschip and i am happy with it. How amazing this freaking small chip shows noticeable output like fuel consumption and all that. Love this product.”

“What a great performance ! I feel much smooth without lag when accelerating ! Thanks a lot”

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

“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″

“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.”
