Anyone run flex fuel, overdrive crank, headers, and a CAI on a Z, and not run out of HPFP pressure? Lift pump is stable at 58psi or higher.
Trying to see I'm looking at this the wrong way. I would think if I was getting everything from the HPFP, that I would get a drop from the lift pump.
Am I just way off expecting that?
Currently can't get pressure to stabilize. Drops to 8MPa before I lift around 4500rpm.
Also, can anyone offer some insight into what the duration max value represents? Stock is 130.
Thanks.
