i want to say 35-37 ish?
stock. use it if you want, what FPR is it? b and m command flow? if it is anything that you have to cut the top off of the stocker, sell it. the stock reg is good for more power than you will prob. make at that boost.

set it to where when you pull the vacuum line off at idle the pressure goes to about 45. then when you connect it it will go down into the 30's that should be just fine.
on boost. it is more based on what happens while tuning. if you run FMU it dont really matter if your tuning the tuner will set that for ya

ok here is the deal.
line on = no rise in fuel pressure. idle.
line off = atmospheric pressure. wide open throttle fuel pressure. remember there is no manifold vacuum at wide open throttle.
the line off method is for setting what we call base fuel pressure. it is the highest it will be without boost acting on it.
if you are goin turbo on the stock pump, it is a matter of time before it or your engine will expire. replace it with a walbro.

no because that will be like 55 off and 70 when boosted.
replace the pump, leave the reg alone. thats what i would do.
32 bucks for a reg and gauge, its your engine. me i wouldnt trust it.
