racerat, how are you only seeing 15.6 psi w/ a 15# upper & 6# lower....:??:
i'm currently running at 11# upper w/ 6# lower & see 15#...
I'm only off by 1.4# according to that chart.Originally posted by coleman
but even a 3.5" upper & 9" lower should yield 17# according to Kenne Bell

I've commented serveral times that I'm making less boost than I'm supposed to, but I am seeing the right amount of power.
The boost amount has been measured two ways...autometer gauge and autotap. It does the same thing on the dyno and on the street. It's been dynoed twice with the same combo with the same results.
I have a 3" exhaust so maybe it does breath a little better. Not sure.

Nope. Maybe it's my halfshafts??Originally posted by coleman
i've got the QMP 3" exhaust but stock manifold.
racerat, do you have headers?
