Default Not building boost

The car is an 89 crx si with a TD05H, dsm 450s, external WG @7 psi, 1g DSM BOV, TurboEDIT.

The car is running extremely rich right now, but I've asked about that in another part of the forum, my question here is I am not building boost. I don't have any exhaust leaks, I don't have any vac. leaks, the WG works fine, what else could this be? Could the BOV be stuck open? How do I check the BOV? When the car is in neutral the boost gauge sits at about 17 in vac, when i rev it in neutral it jumps up to 0, in 1st gear when I rev it up to about 5,000 rpm it doesn't move past 15 in vac. any ideas, please throw them my way.

Charge pipes are hooked up and tightened.

The gauge responds (goes from -17 to 0) when I'm wide open throttle in neutral.

Do you feel a kick in power?
If everything is working right and hooked up, then it must be your gauge.
Otherwise something is leaking air, bigtime.

If you clocked the center section of your turbo you may not have moved the wastegate in all the way to seal. It may be open and you dont know it.

Well, I found the problem, the turbonetics Deltagate II has 2 vac. ports on it, the one I have running to the intake manifold, the other one I had blocked off. I opened it up and I've got boost.
