[SuperCharged00GT]

i am thinking of changing the boost pulley on the saleen supercharger...i believe it is running 6.5 psi at the moment i would really like to take it up to 9 psi, i have the saleen intercooler, motorcraft fuel rails, n all the other goodies that need to be changed for a supercharger...is it as easy as changing the pulley n instang hp or do i need to adjust fuel injectors, timing, and ecu?? thanks!
