Default Adjust FPSS or bigger fuel pump

FPSS not letting system hit. At 75 shot.

Don't do anything untill you know what the fuel pressure is at idle and then under full throttle.

What is the FPSS pre set at? I agree with terry s, try to watch your FP during a run. If you drop more then a few psi let off and I'd say it's time to upgrade the pump.

Agree'd. Get a look at FP idle, and WOT, then compare to the FPSS setting. Although it never hurts to replace the stock pump, if its fine why spend the $.

I want to say they are 32 psi, but could be 35 psi, I'll have to check tomorrow morning.
