Hi guys!. Im trying to work out this tune on my truck, but it seems no matter what i do, I cant get fuel up top from 3500 to 6400. Running 15's on the wb. Would you guys mind looking it all over and let me know where im going wrong?
build is as follows
6.0l, 10.8:1 243 heads, tsp 228r cam on 112 lsa, truck intake and tb(78mm), flex fuel injectors(so i was told) long tubes and no cats, 3000 stall 4l60.

Thanks in advance for any help.

Here it is

[qwkvert]

The injectors are 12587269, so they are suppose to be 38lbs/hr. Just checked them.

Is your FPR manifold referenced...?

What did you measure rail pressure (with reference hose disconnected)...?

[qwkvert]

58ish at the rail. Yes it's manifold referenced.

Need to measure it +/- 1 psi.

Need to measure it +/- 1 psi.

Your tune is MAF enabled. If your top end is lean then your MAF curve is wrong.
