I have a 1997 GTP. I have already put a 3.5 pulley on the supercharger and a cold air intake. I do not want to tear into the engine untill I have to is there any other mods (Throttle Body Spacer, PCM) that would help me anymore that would be worth the money? If so is there any thing I would need to change (plugs?)

Welcome to AF.
It depends on how much power you are looking for and how much money to spend.
You would benefit from a re-programmed PCM module. Relatively inexpensive at $99 or less. Recommend ZZP, Intense or ZZP. Do you still have the u-bend after the CAT convertor? Hi -flow Cat convertor along with a u-bend delete.
With the 3.5" SC pulley you should be running at least one range colder on the spark plugs. Most of us use Autolite Copper Core.
605 - 1 range colder
104 - 2 colder
103 - 3 colder
