Proper normal fuel pressure range
 
On my 2006 ram, what should I be expecting for lift and rail pressures? I.e idle and WOT...

I believe 8-10psi is the normal for stock oem pumps. Rail pressure you should see

5k-8k at idle
12k-18k normal driving
24.5-26k wot. You don't wanna see any more than that. Or you'll be putting a new release valve in over some time.

ok, my CP3 has got to be wounded then. I NEVER see more than 20k even at WOT. Even on Lev6 with the edge.

You may be draining the rail. Do you have a lift pump upgrade??? And have you been keeping up on your filters???
