bigger injectors same duty cycle
bigger injectors same duty cycle i had 60# injectors, 300lph pump. 10-11psi and i was at 110 % duty cycle only injectors. so i bought a new set of 80#'s which at 60psi flow almost 1000cc. and with everything being the same except for the injectors my duty cycle is about the same. could it be my pump just cant keep up? any thoughts/ideas?
both sets of injectors were siemen dekas and my fuel pump is a stock toyota supra tt 300lph pump.
thanks!

Log fuel pressure, log AFR's, log injector pulse widths.
Unless you now what fuel pressure is doing, nobody can answer. You make no reference to AFR's so again, nobody can say what might be happening. Nor whether you are asking more or less of any injectors.
duty cycle as a number isnt really important as long as you dont run the injectors flat out.
And if you havent changed anything other than the injectors, of course DC's will be the same, but there should be a ton more fuel going through the engine
No useful info.
