Administrators BRAAP Posted March 23, 2007 Administrators Share Posted March 23, 2007 What EFI intake manifold are you using, OE N/A, OE Turbo, aftermarket? Quote Link to comment Share on other sites More sharing options...
CantZme Posted March 24, 2007 Share Posted March 24, 2007 ditch the 2mm hg, it'll just lower compression, which is already REALLY low @ 7.4:1. Off boost response will be horrible and the stock compression can already handle an excess of 20psi(depending on mods)...ditch the HG, it'll only hold u back from your goal of 275 WHP Quote Link to comment Share on other sites More sharing options...
