Does anyone have experience with the Polestar engine performance upgrade? They are stating big numbers, particularly the torque and because it is factory authorized the warranty stays intact. Does anyone have any direct experience?

Title should read C30 (can't edit)!

 

I came to say something about title, but sadly you noticed haha.

If you get to keep the factory warranty i would say it's worth it. How much do they charge?

 

I've heard pros and cons. Personally, $1200 is a bit too much for 25 extra horsepower. I think the C30 already has plenty of power.

 

Guess I need to update this. Changed my mind and got the Polestar tune last week. Very impressed, I really feel the engine is stronger, especially in mid-range. Full throttle acceleration seems to have different shift points, it holds gears longer. Overall, glad I did it.

 

Thanks Bobamoo...holding each gear longer sounds like a good thing. I will consider it!
