Understand, but the vendors on this site advertise 75 RWHP with the 10% OD pulley, CAI and a tune. My numbers reflect no where near that. I do understand 91 octane will lower that a bit. The 125 RWHP kits from vendors advertise 125 with long tubes,high flow cats, injectors,10% od pulley, CAI and tune.

My increased output is 41 RWHP, not 60-70. Maybe your quoted numbers reflect an automatic? I am a manual. By your metrics I am 19-29 RWHP short.
