What rail pressure?
I have read some other threads about this but none seem to answer my question.
With the TST turned off what should my rail pressure be cruising @ 2000 rpm?
I have read 20,000, but i'm not sure if that is stock or with a power adder.
I am seeing about 8-10,000 psi is this ok?

Thanks,
Chris

Sounds about right to me. 20,000 would have to be with a pressure box on.

Okay, forgive me if I am missing something here, but my bone-stock '06 is running 18K cruising at 70 mph?

Yes they increased the pressure alot on the 04.5 and up. I will see around 15-22kpsi running at 70-75 with my pressure box.

Gotchya...thanks. I thought that might be the case but since they are both common rails I expected them to be a bit closer in pressure.

Does rail pressure drain to zero when truck is shut off? How about with a rail cap?
