So I'm not an owner yet, but I sell Volvo's for a living and that brings me to my challenge. I'm looking for a 2008 ish manual C70 that I want to tune up. I'd like to get it to 300 crank... just because. The polestar tune gets me to 250hp and 273 torque. Living within the parameters of the tune is there any real way to get to 300? The reason I'd like to use Polestar is for marketing. If I can tell folks I have it I can better sell the product. Mostly cause it's cool and builds brand loyality, there isn't really money to be made selling Polestar. However, I'm guessing I'll need some hardware adjustments that the tune won't make use of. Sorry I know it's a noobish question. I can rebuild an old motor but am just starting to learn about computer management etc on newer cars.
