Mustang falling on face after mods installed

[Dark_5.0]

Ok here is your problem. You are running 38psi on 30# injectors wich is making your engine run pig rich.

30 pound injectors are really too big for your light mods. You are going to have to turn your fuel pressure way down wich means you need an adjustable fuel pressure regulator. 24# injectors can put over 400HP to the wheels on an all motor set-up.

Double check your firing order etc...

You are way over-injected and when you add that to the crappy SN computer, IMO there lies your problem.

30# injectors car support 400HP at only 36 psi.

Good luck,
