jcboekl you are on the right track indeed. That's what I'm trying to make who ever's reading these charts understand. If a filter creates enough backpressure than you will get an initial tq jump, tq and backpressure go hand-in-hand! The AFE was designed to minimize Back Pressure. Comeon Guy's if you spoke to someone who actually
RACES on a regular basis (someone like me), I would tell you, 'Why would you be so concerned about driving this High Revving Motor in such low REV's, I sure don't!'
