Hey, i run a 1999 gtp with an air intake and catback exhaust. I was wondering if it was safe to run a 3.25 inch supercharger pulley with a reprogrammed pcm. Also i’m looking for a pulley puller to either buy or borrow( i will give u some money) so that i could install the pulley. If you know of anyone selling any gtp parts please let me know. thanks
yes although its recomended you get 1.9 rockers and a down pipe. but first a scan tool (scan master. snap-on, ect) to moniter kr and spark advance is your best freind.
you can rent a pulley puller from places like auto zone and so on.

Not these ones:mad: Jim,just like i told you and gnocide said too,you need either rockers or headers,on few occasions i have seen very few people run a 3.25 with none of those and be fine. You need to get that 3.4 on first and run it for awhile till you atleast get rockers. You,ll learn:D Oh and john…spark advance OWNES you:D
3.25 pulley and what reprogrammed PCM? If it’s a GPS PCM, no. Maybe on a custom DHP, but I doubt it seriously. Do the 3.4 as SleeperGTP has said.
