my cousin is wanting to put a pulley on his 01 gtp. has all the support mods. hes going to a 3.4 pulley i believe. i dont know alot about forced induction, he wants me to tune it with hp tuners. ive done some basic tuning thats it.
i know im supposed to look for knock retard when i scan it. youre supposed to change the high octane timing table to get rid of the knock retard, correct? if so how do i use the scan data to know how much to change the timing? is there anything else i need to tune?
