Yea no worries mate, umm yea bout the tune its hard for me to explain because Im no mechanic. But because Im a little slow & cant explain myself better. Basically when the convertor locks up, instead of it dropping 200 ish rpm it drops 500-600 rpm. Im only going off what it was standard & it never dropped that amount of revs before. But at the end of the day its my fault for not explaining myself better Btw, did u end up getting 300rwhp yet?. Ive got 310 but obviously its a mafless LS1. I actually thought Id get more out of it standard but oh well, its fun none the less. Oh & talking about fun.....I just bought myself a new FPV GT-P wow! If you havent driven one...please find one & take it for a spin. I know its a ford....but holy f@$k!!. Only downside is the 80+grand
