Hey, not sure what to make of this data. Just finished up a boost referenced return fuel system install with 2 x Walbro 460 (staged), base pressure is set at 50psi. Running around 750hp at the engine so should have heaps of fuel.
When I calculate the delta pressure from sensor volts I'm +/-1 psi off base pressure in all driving scenarios so I think yah, the world is good. But when doing the same using the fuel pressure PID, in all scenarios except WOT everything follows nicely, but WOT takes a dive like I'm out of pump. I have tried multiple PID's and they all read the same. I don't know which reading to trust.
FYI
Calculated delta pressure from sensor volts (P/N ACDELCO 13516496, Gain 27.809, offset -20.717)
(Gain x Sensor_Volts - Offset) + (Baro - MAP)
(27.809*[6507.10]-20.717)+([50032.98]-[50030.98])
Just wondering if anyone has encountered this before and can offer some guidance as to how I should interpret.
