I suppose if you crank up the operating pressure, the injectors will support 450 hp? but the system is designed for a lower operating pressure (as well as a shorter duty cycle) and raising it knocks things out of wack if your using stock electronics which try to compensate for the irregular injector flow.

The computer could actually care less about how much hp the engine makes, how much air it needs, or how much fuel it needs or even how big the engine is. Heck it could care less what type of engine it is on (well within the realm of 8 cylinder 4 stroke internal combustion engines)

What it sees, is the MAF is using this much voltage so I'll compare this to the voltage from the the throttle posistion sensor, and what RPM the engine is turning and apply voltage this long at the injector so when I check the voltage from the oxygen sensor it should compare with the table and look like this. Leading the computer to say "kewl" or "opps".

When Ford designed the table, they had a specific pressure operating range in mind so the injector would flow this way when there was this much manifold pressure observed. Cranking up the pressure at the injector changes its flow characterisitics, which forces the computer to alter its operations in order to comply with the table Ford provided as best it can.

The whole trick to selecting an injector and a meter is to maintain resolution within the operating range the sensors were designed to accurately read
