So I've got a completely built block (9.1 forged pistons, eagle rods, arp bolts etc.) and a mild port job on the head with mildly port IM. I'm running a 255 walbro intank, 310's and the greddy blue box, FP is set at 36psi with hose on. (7psi of boost) I think that my motor is running very rich, cause on the freeway whenever i give it about half throttle anything under 4000rpm (especially in 5th) the motor bogs pretty bad. I have the autometer guage(i know they suck) but it shoots to all the way green whenever it bogs. Uberdata is on the way. The question is should I turn down the Fuel pressure to say 33-34 would that alleviate some of the bogging? keep in mind i dont want to run lean while boosting above 4000. will the blue box compensate enough?

 

Green just means richer than 14.7:1. Useless.
