Hello to all, I just bought a 2007 GT 500, I want to do many performances improvements not sure where too start, perhaps I can get so help. What is the best cold air intake ? pulley system ? mufflers ? Fuel injectors ? need some advise .
Advice I received: install smaller pulley for each half inch smaller gains 4 psi boost with factory supercharger; cloth/oiled air filter yields larger pores for increased air flow and oil traps debris; bigger injectors so OEM ones are not operating at max rate; SCT's SF3 or X3 tuner. Overall hp yields will be nearly 100 rwhp; Finally spend couple hundred $$$ and dynotune for maximum power gains.
