I have many mods also but I never see much over 30 psi. Banks ic and elbow egr delete fass 150'180, afe stage 2 , head studs, and exhaust. PPE 215 hp tuner. I didn't think that the stock turbo's would make much more than 30 psi? I always thought that usually when they spiked higher than that a vane was sticking. Dunno? With these mods I am at 30psi boost 1600 egt's and 40 fuel press at wot. I think it is time for a regulated return to get my fuel press up. Does anybody run one?
