Question about running rich...FPR setting+walbro+310's
Si 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?

Re: (Muckman)
i guess no one is understanding what i mean. Yes i know that the fuel pressure is static and no way to distribute, BUT what i want to know is where is a good point to leave it at right NOW in order to not lean out up top and not bog down lowwww. READ the post before posting

I would just leave it alone until your uberdata is setup. That's what I did. I decided it was better to run super rich in the low RPMs than risk running lean up top. After all, lean blows motors and rich is virtually harmless.

Re: (HollywoodEG6)
Im having the same problem, my car is running way rich( like around 10.0 to 10.5) at idle and low rpms, under 4000, but when im in boost its 11ish. i have my safc a/f set at -50 from 1000 to 5000 rpm. my fuel pressure is 43. ive tryed taking my fmu out, that did not work. ive been thinking if i got a fuel pressure regulator, i might be able to turn down FP then correcting the a/f using the safc. im scared of blowing up my ring lands or rings due to the amount of fuel not being burned. if any one has put a fuel pressure regulator to fix this problem please post something
