Your pressures are right in line. It tells me the lift pump is healthy, and supplying the injector pump what it needs for its curent demands. The book says the minimum is 3psi at WOT. Mine will go down to 0 with stock injectors and some pump tuning. The max for a stock-internal VE (no clips to hold the front seal or anything of that sort) is about 18-20psi. After that, you start "making oil." If you find your fuel pressure dipping on hard runs, you can upgrade to a low pressure piston lift pump- Cummins # 3936320

Johnny Cetane- those sound like maybe 2ndGen 12v pressures, though I didnt know they got up in the 30s. I know the P7100 can handle more input pressure than a VE.
