Mods in sig i made 395 to the wheels thru a auto running 11lbs so my question is how much of a difference will the pulley swap make? And what psi should that put me at?

If you go to 3.12" pulley you will make 13 psi, a gain of 2 psi or approximately 40-50 rwhp. I am running a 3.125 pulley with blower cams, on stock heads with no long tubes.
