What timing are you guys running in that area of the curve on 10psi pump gas?
I have a buddy that is street tuning for now until I get back to the dyno. (1.5 hrs away)
were at 9* right now

I agree. This truck is 9.6/1 compression so I think
I have that saved in my phone but it’s hard to show that to someone tuning your car and say, “do this”
I think I’ll try it though. He’s a good buddy so maybe he’ll listen.

Are you keeping an eye on fuel pressure? I'm not sure what that pump or what the injectors flow, but 400 to the wheels might not be far off for a stock application injector and fuel pump on pump gas. I mean, swinging for the fences, 80lb injectors make what 650-700 on pump gas?

The stock LSA injectors should take you to 500rwhp with 58 psi fuel pressure and 11.5 AFR, maybe a little further depending on max RPM.
I would make sure you are not losing boost somewhere, the power essentially flat lines at 4700 rpm, it should continue with an upward slope throughout RPM range.
