Will a PCIII give me a noticable porformance gain? I have an 03 750 GSX-R with a full yosh exhaust.

If installed and calibrated correctly it will maybe give you 10 extra ponies at the top end.

If not installed correctly could give you major repair bills and calibrating it correctly I am told is a little like stacking BB's in the dark.
