My car is a 98 model and still has the NPI heads..at what RPM should I be shifting at? Also- what mods would raise or lower that shift pt? I am planning on installing a shift light with a specific pill to shift at..At anything beyond 5,600-5,800 it seems as tho im jus running the hell out of it wi no power gians.
thanks for the help.
