Wow, that's speculative. Boost varies a crap-load based on numerous things..... vehicle speed, throttle position, selected gear, engine RPM, engine load..... Not really possible to give an actual number at any RPM.
However, seven pounds doesn't seem too bad as a basic range.

That all varies greatly , 4.2 -5.0 cars are different, mods or no mods all makes a difference

I think he means what is the max boost it gives when flooring it.

~5000rpm. It's absolute pressure, so actual boost is 14.7psi
