The problem you run into is this, as long as you keep your foot planted in the pulsewidth will remain constant, the hpop will drop, causing poorer and poorer atomization of the fuel the more it drops.
With a big oil truck, the same amount of fuel is delivered only the hpop doesn't drop, therefore the atomization stays up and the fuel is burned better. Make sense?

but, with the drop from the HPOP.....there is less fuel....No????? at least at or close to WOT???....and, WOT is where the highest volume of fuel is injected....which means if it is burnable...it should lower EGT's and raise cylender temps....i have been going off of what you discussed with me in PM for my assumptions on my theory here...tell me where im wrong or right in your opinion.....
