Re: curious about tb mod

The pump runs continuously, delivers constant pressure, and the extra fuel is returned to the tank. More demand for fuel does not increase the work done by the pump. It's just a coincidence.

But to answer your question, yes, the PCM does know there is more air. The Mass Air Flow sensor reads the amount of air coming into the engine and increases or decreases the injector pule accordingly.
