Boost Controller questions...

I just bought a little bleeder-type boost controller for my SPG and it just won't work. I had it adjusted all the way out, so it bled off the maximum amount of air, but the boost didn't raise even 1 psi. When blowing through the valve and adjusting the knob, it works as efficiently if not better than my friend's TurboXS MBC, which gets him above 20 psi on his volvo? This just doesn't make sense. My turbo is fine as with the wastegate hose unplugged it'll boost until I let off. Is there something about saab wastegates that require more air to be bled off? I tried another MBC on my last SPG and it had the same effect- nothing. The only thing I could think of is that my wastegate is adjusted too low (about 3 psi) but even then it seems the MBC would have to make SOME difference. Thanks in adavance.
