It's very important to keep this in the proper context, I said you can easily make 250whp on 440cc injectors with stock fuel pressure. As Erik said with stock injectors using an FMU you increase fuel pressure to get the proper amount of fuel.
So -
stock injectors - use FMU to increase fuel pressure=increase fuel
-
big injectors - stock fuel pressure, change pulsewidth to increase/decrease fuel
In either case you must use a better than stock pump, I use an in tank Holley Forced Induction pump (255lph) there are other brands available
