slow boost

My 93 9k aero has recently become significanly slower than normal. The car doesnt pull very hard at all untill 5k rpm. The boost is coming on late and slow. In third gear it doesnt make full boost (~15 psi) untill 4.5k rpm. Three weeks ago when I dynoed it it would make full bost at 2.8k rpm so something is deffinatly the matter. I pulled the spark plugs and they all were the right gap, although they had a slight whitish tint on the electrode. The bpc valve is working and the car is running ~5 psi base boost. If I pull the parking brake in third and floor it at 3K rpm, it only makes ~7 psi. COuld there be a leak in the intercooler or could it be more serious like the head gasket(although vacum pressure it the same as before, 21-22 in hg).
