<< what mods have you done to it? >>
Um, lets' see.
1990 5.0 Mustang
Supercharger (6psi)
73mm mass air
Headers
catback
Ignition
Tremec 5 speed tranny
air filter - basically everything up from the intake... pipes, mass air, throttle body, etc.
That's msot of the significant stuff. The car's not tuned real well for performance, though. I'll get that done eventually.
