If you took the airbox off (introducing more air) and it ran much worse, then Id say you need more fuel (either need a bigger main or a restriction somewhere in fuel delivery). Let us know what jets you have in there to compare with the jetting database.

94mm bbk, +4 stroker, Hot Cams, Vertex piston, FMF Power Bomb header and Power Core can, KW black diamond valves/dual springs, FCR39, K&N, Elka long-travel LT fronts and rear, Houser +3, +3/4 LT A-arms, American Star pro xs chromoly tie rods, Dyna non-programable, Tusk +3 axle.
