Higher RPM means less fuel needed to maintain it.

What you are seeing that code for is your Chip is calling for more fuel than your HPOP can provide.

Upgrade your HPOP

See that the filter for the hpop is clear. Its in the bottom section of resvoir. Load created a greater volume demand.

here's what my problem was in a somewhat sim problem, only mine was more extreme..have an inlet restriction test done..very possible you have debris in the fuel tank..higher fuel demand sucks up the debries and clogs the fuel pickup screen. shut her down and the demand stops..thus the debris drifts back to the bottom of the tank...until the next high demand, especially on an uphill grade.

is the filter for the hpop part of the pump or part of the housing? on it's 3rd pump but if filter is part of housing does'nt mean ford checked it when replaced pump.

have heard about fuel pickup being clogged before, have a pre-pump set-up from sinister on order now.

thanks guys, will keep everyone updated
