Dreamer, I have a quick update for you. I had the guys at MAC Autosport swap out the 3.2 inch diameter pulley on the blower for a 2.85 inch diameter pulley, swapped out the bosch bypass valve with a Forge direct replacement that uses a piston instead of a diaphram and got a re-tune. Final numbers are now: 398 WHP, 319 WTQ at a little over 8 PSI.
