someone educate me on stock lift pump pressures on an '03

put a fuel pressure gauge on a freinds '03 ...

he's got a tst box ... ps 62-14 ... afe intake

at an idle he sees 6 p.s.i. post filter

with any throttle at all with tst on 3x3 and up his pressure drops to 1 psi ...

we figure it's time for a fass but just wondering what the stock pressure should be at idle and does a tst on low settings drain the stock lift pump almost instantly under normal circumstances?

thanks
