Bone stock until fairly recently, my '91 ran 10-11 lbs. Could swear it's more like 12 lbs now with the intake, MAF and exhaust. Hard to say, since it's not lined off. Rarely push it hard enough to find full boost though. Pulley isn't on there yet.
Sounds kind of low compared to other listings here. Vacuum is at 20, idling, 24 in gear when let off the gas, so I think everything's sealed up well.
