Default stock injectors and FPR..

ok I was told that having stock injectors would mean adjusting fuel pressure with a FPR would do me no justice?
And I also heard that a FPR doesn't matter if I im running rich and I was told that because running rich is the Air to fuel ratio, now im confused as hell lol.
let me know if I cna correct my richness around high rpm with a FPR and stock injectors please...

Well your injectors don't tune. That is just how many lbs. of fuel they flow per hour. It is really hard to tune with a stock FPR. Best one to get is from www.dallasmustang.com. Kirban AFPR (Adjustable Fuel Pressure Regulator). $69.99. And it's billet baby.

What does your fuel run thought our the rpm range?
I dont know exactly right off the bat, my dyno and afr sheets are in my room somewhere, I start a lil lean at 14 and higher rpm it starts to dive quick....
