8* KR that's who! 
I seem to be running lean in boost. I think I'm going to need a bigger fuel pump. First of all I removed the FMU when I installed the 60# injectors. I don't think the booster pump can keep up(190 LPH I think).
Just for kicks I tried to figure what was going on flow wise. I'm not sure if this is exactly how it all works but the figures come out about right.
60# injectors flow 70.47 #/hr @ 60 psi
70.47#/hr= 44.4LPH X 8 cylinders = 355.2 LPH (100% IDC)
My truck is leaning out at +- 40% IDC = 142.08 LPH
190LPH walbro inline (p1sc kit) = 158.98 LPH @ 60 psi(13.5v) or 121 LPH @ 12V
I was goining to uprade to a 255LPH intank anyway. I think this should fix my KR issues also.
Opinions?
