Ok here is my setup-vortech SFMU 2.72 disk,accell #30's, 14B, Startion FMIC, walbro 255lhp. 9psi. forged crap bla bla bla My problem is as soon as I hit 5500=6000 rpm, my power drops off drasticly. (this is at WOT of course). Now here is the strange thing, if I let off the throttle just a tad, say leaving it at 95%, the power comes on stronger than ever, still at 8-9 psi. O yea she also spits and coughs when im at WOT and in the higher rpm range. So what gives here?
