Hey guys, i've got my car running at about 7.5 lbs of boost right now, what's a good fuel pressure to have for only 7 lbs?

IF (and that's a big IF) you had a custom tune and just turned up the boost pressure, add 1 PSI fuel pressure for every 1 PSI of boost increase. That keeps the injector flow at the same point it was before you increased the boost. That will maintain the Air/Fuel ratio setup in your custom tune.
