tune and mods
Hahns PPC is canned, and the stage kit would be considered canned. And lets say you want to keep warranty and use the late stage kit and not retune. Would it be best to have all parts installed prior to get the ecu flashed, or would it really matter if you added them later? Performance wise, would you get the same hp/tq rating if you added them after the kit, or before?
Wouldn't that be great to have a learn-up feature. It'd be a self tuning car in the same way that learn-down works.
