ok there is a vacume line that comes off of the throttle body and goes to a valve with a electrical connection on it which in turn goes to the bov. now my question is there is no vaccum comming from that port on the throttle body or if there is not very much at all so why would it not have vaccum because it seems this controls the bov and doesnt seem like it would be doing this with no vaccum but havnt noticed anything weird....

If you hook a boost gauge to the bov line, you'll notice that it never gains pressure, in fact, the only time the gauge reads anything is when you let of the gas, and then that little electrical valve opens, and pulls the dump valve open.

There is vacuum to it, comes off the throttlebody. (the part that has 2 nipples on the one piece of plastic) If you weren't getting vac there you'd have a CEL.
