I am running a BEGI fmu but the lowest fuel pressure i can get under boost is 105 lbs. the needle is out 4 turns and will not change the pressure. i am running 6lbs of boost. any ideas?
thanks

around 90 +/- psi is where you want to be, you could turn in your adjuster a hair. But any changes should be made on the dyno under load to be sure your AFR remains safe. Be sure your gauge is working properly first by checking it with another gauge.I am trying to lower my peak pressure to around 95 psi. Is 105 lbs to high for stock injectors?
If your AFR is 11.8 I would say everything is working just fine.I am running an Innovate LC-1. my A/F under boost is 11.8:1. Turning in the needle would raise the pressure, i want to lower it. Is my A/F correct?
on the begi the further in you screw the bleed screw the higher the rate of riseI am referring the rise rate screw, in would slow the rate. Big question is something wrong?
gotcha...I got it backwordson the begi the further in you screw the bleed screw the higher the rate of rise

I agree Ryan that is a sweet unit. Aeromotive also makes a quality unit as well.Yet another FMU problem. AEM FIC with a 1:1 regulator would solve all your problems

Be safe and get a new FMU, cracked once it will again...good news though.UPDATE: I finally found the shims and discovered the upper one was bent and the lower was bent and cracked. I made a .010 shim and installed on the lower side of the diaphram against the in-out block. I set the low side at 40lbs at idle and it remained stable. I will check the bike under boost tomorrow, but i am sure the problem is cured.
Thanks for the advice
actually that is what is usually done is replace with a .01 shimBe safe and get a new FMU, cracked once it will again...good news though.
