What PSI should you see LP at idle?

I just installed my quadzilla RP gauge with lift pump kit. All went well . i see 6000-7000 psi idling (rail) and 6-7 PSI idling at lift pump. Is that good for the factory intank lift pump. My truck is a 2004.5 but it has the pump in the tank.

sounds normal. Stock pumps have an inline regulator right in the tank. The are designed for volume not pressure.what do you see at WOT?

I think you are right on with those numbers. Like syndacate said, how about WOT?

FWIW, after I got a FP installed on my 05, it idles at a solid 9# and at WOT drops to 6#.
This is on a bone stock truck by the way.
Hope this helps.

I have 8 psi at idle and can draw it down to zero with my Bully Dog.
AD100 is next on the "to do" list.

I see 9-10 PSI at idle, and it'll pull down to 4 WOT with the Smarty level 9 at the drag strip.
