I am having trouble figuring out where my fuel pressue should be at. At idle it sits around 35 an jumps when I hit boost. Here are the mods

T3/T4, FMIC, HKS SSBOV, MSD 6-BTM, Vortec FPR, Magnecore wires, Deltagate 35mm wastegate, Airtex Inline FP, Apexi Cat-back, AEM Fuel Rail, Missing Link.

Originally I had a Holley 255 on the car with out a inline and was running around 40 -45 psi at idle, took the holley out, put the stock back in and added the inline and now I am sitting around 33 - 37 psi. Should the PSI be higher at idle? As soon as I hit boost the fuel gauge shows it increasing to compesate for boost. At 5lbs the gauge is maxed out. The gauge reads to I think 100 PSI

 

what kind of injectors u got in there.??

 

I am still running stock injectors.

 

one more thing..what psi are u running ( on your turbo)
and what motor...??

im assuming u have the 12:1 FMU ..right.??

 

It is the LS motor, I have a 7lb spring, but I have never gotten over 6lbs. Any ideas why that might be happening? yes, I have the 12:1 FPR. It seems to work pretty good. At about 1 lb it goes up about 12 psi on the fuel gauge.

dont need that much extra fuel at all until 3PSI, you may be way too ricj for your setup.
Af???EGT????

 

My EGT usually runs between 1000 and 1400 farhenheit. I was throwing codes for being too rich, but I leaned it out on the AFC.
