Fuel Pressure Question

[my85grandnation]

I was just curious as to what everyone else's fuel pressure was running around. I have a basically stock 85 T-Type, just have a K&N, custom exhaust and a ATR chip. I hooked a gauge up to my car and at idle line on it was about 30psi and I thought that was kind of low. Line off it went up to about 40psi, and while driving around if I got all the way into the gas it went all the way up to 50psi. Do these #'s sound right?

It is supposed to be measured/adjusted with line off. 40 is fine, if it was 40 with line off then that is abnormal. Does it go up equlivalent with boost? Meaning 10 psi fp with 10 PSI of boost.
