June 22, 2008i have a wheatley tune as well. the 93 octane one with shift points at 6000 rpms, 75% TM off, and 25% firmer shifts. does anyone else notice that past 5800 rpms that the engine seems to lose power? thought of changing my valve springs to comp cams beehive springs and maybe adding longer rocker arms. do you think that would help?
maybe i need a retune?
