[QUOTE="dmp0001, post: 15765464, member: 189536"] I have Pypes Long tube catted headers, full 3" exhaust a high flow intake and a 90mm TB. I'm not sure how mods affect my psi because I had them on before I added boost. I think it's the altitude killing me (6000ft). But I am right at Vortech's claim of 7.5-8.5psi. I am also keeping my redline at 7,000, I know people see more at higher rpm. My real question is which pulley will net me about 2psi. It seems no one really knows for sure so I guess I'll try the 3.48 and see what I get. [/QUOTE]
