looking for help on boost problem.....

I'm having some difficulty nailing this problem down and I thought I would use this board for some helpful hints....
here is the problem.... my 1995 Saab 9000 should be hitting 20-21 p.si. and it is not. I hit about 19 p.s.i or so and then as the r.p.m.'s go up, the p.s.i. drops to about 15 p.s.i. I don't think that I have a leak as the vacum reading at idle seems good (it is 20 in hg). Most likely the problem is with the boost control valve... at least that is what I thought until I put another boost valve on. Same result - good idle and p.s.i starts at 19 and falls to 16. So, what else could my problem be? Blow off valve?
As always... TIA!
