advertised boost is 10-11psi depending on how high you rev it.....I ran it and got into the 9's with it but to this day I don't know how much boost it makes as I don't run a boost gauge...143.86mph best though...
i am almost done tuning the 3.6" pulley and saw around 10psi at 7200rpm. i dont have an air filter at all though. there is a noticeable power difference between the stock 3.8 and 3.6 but it could also be that the tune is a bit leaner now. i was at .73-.75 before and now its locked at .79 only reason i don't use the 3.48 is because i was advised against it on 93 octane.
