No you are not injecting more fuel into the engine.

For instance, if I write a program to call for X amount of fuel with a pulsewidth of 3.4 ms, on a stock hpop truck, it will inject the called for fuel in that period of time. 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?
