Default knock,knock. Who's there? Retard. retard who?

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?
