Warranty shwarranty blah blah blah I got that covered. Is the HP and speed increase worse the $$$ (600 USD)
Guy at the tuning shop told me this 540 isn’t worth the money messing with the exhaust system for noise purposes.
But I’m also not seeing much online about anyone tuning the G30 post facelift.
Is the down pipe and k/n performance filter what makes it stage 2? Or did you need to flash tune as well
