From your sig, I would say it's time to upgrade head units or up the compression to get any more power with the P600B>

i was thinking the next step would be to send the heads out..they are basically stock...it would drop compression some as well...then..look into a different blower...i had thought the p600b was leaking from the gasket.or seals..its not..its from one of the oil lines...so the blower is ok for now...but if it ****s the bed, this winter i'll prob send the heads out...and then look at a new head unit...i posted before about that ati f1-c i think its called..specs on it seem wack dont know what it cost though probably an arm and a leg heh
