I have a 1995 Firebird that came with a 3.4 and M5. I just upgraded it to the 1995 3.8 and had Comp cam (.512 Int & .520 Exh), RK headers, Comp springs,retainers and cromoly rods installed. It's still hooked to a 1996 M5. Do I need to have the PCM flashed due to the new cam? I've also had a functional Suncoast Ram Air hood for years and RK cat back exhaust with Random Tech hi-flow cat. Any idea of the power increase I can expect with these current mods? Future: Supersix heads and intake with forced induction (hopefully the kit from this here),3.42 gears, limited slip differential and aluminum shaft.
