Racing - plug it and jet up
I don't go up as many (8 to 10) usually more like 5 or 6 but only cause I bracket race and running your carb lean helps its run more consistent.
Street - running a P/V will help with driveablity (low to mid range) in race trim, doesnt matter since 99% of the time your @ WOT.
Goodluck, Cp
