| hey any of you guy's test out the 17% pully. Any tuning or IC upgrade required? I know you have to get new spark plugs and a new belt, but is that it for the 17%? Is 17% kind of the best of bolth worlds from 15% and 19%? Any suggestions? I have about $500 bucks and lookin for a pully upgrade. Just don't know which route to take.
Thanks
