ok so it looks like i should try the 3.2 pulley for the p1sc
do you guys think i should get the computer re-tuned?
or maybe get 42 lbs injectors
because even now my fuel pressure drops to 55 psi,then goes back up to 60 when the transmission shifts

Yes I would get injectors and tunning. You will also need a inline fuel pump if you don't already have one.
Yeah I would say with the heads and cam you would be down on some boost. Plus belt slip.
