The bigger injector, less fuel psi theory?

Yep! You're right! I'll be the first to admit that I know Jack about fuel injection, but fluid dynamics, I DO know about.

Given the stated fact that the ECU can adjust pulse width ie "duration" of the fuel pulse, if the pressure and/or voume isn't there, then we're not living up to our potential. Right?

Picture it this way, I have 1 bazillion PSI flowing though a 1/32" line, and my ECU tells that injector to hold open for so-and-so milliseconds. Seeing as how that there is no VOLUME behind that 1 bazillion PSI, the fuel pulse will "fizzle", or die out. I understand we're talking milli-seconds here, but with that in mind, wouldn't it be better to have a full "fuel signal" throughout the injector pulse? Think about it bro!

A constant AMPLE fuel supply is where it's at. Carb or fuel injected, doesn't matter. A CONSTANT AMPLE fuel supply! Return, return, return. Send TOO much up front, let the motor take what it wants, and send the rest back to the tank. Trick here is to let the motor have "priority".

Volume DOES NOT equal pressure! But BOTH are needed for a properly operating fuel system. I know what you're saying, and it makes sense. But THINK about it for a few minutes.
