You can run it all day like that on a stock pump too. But really, there's no need; maybe HPOP may not be able to keep up....or because Ford wanted to do it for other reasons.
The desired ICP map is based on mass fuel desired and RPM.
Here's an exercise for you (do this in your head while looking at the map).
From an idle, punch the accelerator pedal.
MFD is above 70
RPM starts at <700
Where is ICP?
What do we know about the relationship of ICP and injector pulse width for a given MFD?
(Hint: check the pulse width map)
Now, using the ICP map, pulse width map, and any given MFD, you can figure out what is happening when you replace that drop with a straight line.
Bonus points for showing work......
