Bypass Valve gone bad? Need advice

I have a '96 Aero, 5-speed. When I first purchased it (used, in early 98), I had to replace the bypass valve TWICE. I think I might need to do it again. Here are the symptoms: Usually my boost needle goes well into the red - now the needle on goes to the yellow-red stripes area and never in the red (it is strangly consist - goes to the same spot everytime). Also, instead of the normal psssst from the bypass valve, I hear a slight flutter in addition to the psssst. From the seat of my pants, I just don't feel the same rush from the turbo.
Any thoughts? Is it the bypass valve? Is there a test that I can do to be sure? Is it a wastegate that is not closing 100%. Where is the boost sensor that works the boost needle located? Ok, I'll stop with the questions. Thanks for the advice/tips!
