Welcome, Daniel.

Could you please explain "dumpers & extracters". Theoritically you could lean out the fuel with the aftermarket fuel pressure regulator, but this would need to be done on a dyno so you could monitor a/f ratio. Other options beyond Intake, Header & Exhaust are some cams, lightened pullies and flywheel. A free horsepower mod is to bump up the timing to around 17-18*. I wouldn't do this unless you have access to 93 octane gas though.
