Ldub, c'mon! Do you really think I didn't search first and ask questions later?!?

Not sure about the S/C pulley size. I also have a modded exhaust, but of course not the same one as Cyrk. I vaguely remember that the curve I'm looking for showed about a +55 HP gain from the two mods. Cyrk is showing +64 HP gain, which would be neatly accounted for by a 5 psi vs. 4 psi pulley. Anyway, that's why I'm looking for it...
