Low fuel pressure 2006.5?

[madmanwithmouse]

I know I saw a topic about this but anyone know what would cause low fuel pressure (not rail). I just changed the filther and it helped a little bit. it never gets above 8, and if im on it hard it goes to 0 quickly . The sender is in the pump. Im running tow stacker with puck off.

How is the pressure with no tune installed??

Sorry, but this was already taken care of on Dieselbombers. Turns out that the lift pump is weak on most dodges, so any added power and they start lacking. I was told 5-8psi is normal crusing psi. Thanks anyway.

That is correct. Mine, however, must be an extra good one because idle pressure stays around 10psi and it never drops below 4-5psi even on a WOT pull. I made my numbers with the stock LP and pressure stayed fine....
