I have a 95 GT 5-speed with shorty headers, O/R H-pipe, Flowmaster American Thunder cat-back, MSD ignition, BBK cold air intake. 215 hp stock + these mods...next im looking at the Trick Flow H/C/I package. how much hp should i have now and after this H/C/I? any idea? also, what all supporting mods are needed with this setup? injectors (what size?), throttle body, mass air flow...anything else? who on here has used this setup and what were your results?? Thanks a lot
