Boost issues

Hey guys, I recently talked to a fellow from Magnuson (hope I spelled that right) - these guys took a Eaton M62 Charger and customized it for TRD it would seem. They explained to me that you could probibly push two more PSI out of the Charger and not get any "detination" (caused by to much compression)and not cause any adverse effect to the unit. They explained that as far as they know nobody makes an after market pully for this M62 unit.

By the way, the low boost on my guage was apparently a loose belt (I had it fixed at my proformance shop) and now read about 6~7 PSI on my TRD boost gauge. :-) I am surprised that I didn't hear it slip??? but it did make a differance in the sound of the charger it self. I would like to try a slightly smaller pulley so if any body knows who has one, pass it along pls.
