Re: STILLEN QR-PRO ecu upgrade
well maybe ppl suck at driving cause the car runs 15.2 stock, and the header alone gives a good chunk of power so if ppl can't break into the 14's then they are the problem.. two tens of a second is nothing especially when you gain as much as 16whp from a header alone... But i guess i'll find out soon enough.. Also the upgraded clutch won't do as much as you think.. it will just engage harsher, and be stronger. as for the flywheel i'd hold off on that unless you autocross or something cause the rev limiter already comes up quick thanks to close gearing and a low redline.. I don't see how those three things would benfit more than over 20whp with bolt ons..
