I just ordered heads and pulley from Tsp.The powerbond pulley is what i ordered.They actually make the pulley for slp. same pulley just one has ans slp logo on it that what i learned when i did a search on pulleys a wk ago.The slp and power bond showed no charging issues and seem to have no belt slipping and does not require a belt tensioner.
most people wait to do there pulley because of front seal issues....you can expect somewhere around 5-7hp...its not worth the PITA of pulling the old one off and adjusting the new one until you actually are doing something under the hood thats going to take some time anyways
They say about 10rw ...
I have a March Pulley, I'm satisfied with it. However I can't say that I felt a SOTP gain. Car hasn't been dyno'd since the cam went in, and too many things have changed on the car since then anyways to get a real feel for what I picked up.
I'd probably go with the powerbond if I had to do it all over again though.

I went SLP, but the Powerbond is the really same thing. I noticed a HUGE SOTP difference, but I imagine most of that was from the heads/cam/intake/header swap rather than the pulley 
exactly what he said did mine with my ms4 swap
