I have a 01 Gt with a Saleen Supercharger, I always read that puting underdrive pulleys is the best hp for the buck, but can I install those and have my SC in a correct tune?

If you make the crank pulley smaller, the one that drives the blower, you will lose boost for sure. The only way you can do it is if you make the serpentine belt portion of the crank pulley smaller, but leave the blower belt pulley the same size.

If you're talking about a smaller pulley for the Saleen supercharger, I know of only one place that makes them, and that's Chicane down in L.A. We installed one of their 66mm pulleys on a customer's car, and it added a bit of hp, not a lot. The Saleen blower just doesn't put out a ton of hp, even with the smaller pulley.

Saleen superchargers are only worth about 8psi according to Saleen.
