Default Boost Leak? Stall Issue

Hey guys. I've been having some issues with my 06 STi for a while. Its on a Speed Density tune so its a little hard to diagnose issues not to mention that it'll still run with a vacuum leak. The issue started when I did a pull and parked the car. I realized the next day that I didnt have any boost after 4k rpms and especially at WOT. I later found that the hose from my Tial bov was disconnected on the opposite end. To me and all of the diagrams that I've seen, it looks like it came from the nipple on the intake manifold under the throttle body. So I plugged it in and shouted VICTORY! But to my surprise , when I started the car it just shut back off again. And now I cant get it to crank without pulling that bov hose back off. I even tried to reset my tune. I'm going to add my mods list just incase it'll help with any suggestions. Any help would be greatly appreciated. Thanks in advance.

Hmmmmmm.....can't comment on boost issue, but, WTF you mean it won't crank?
Many issues may not allow it to not start, no crank is (in my mind) is totally separate.....

So......it won't crank, or it cranks but won't start?!?!
Did you kill the battery while trying to get it started?
Did you disturb a battery connection while trying to resolve your issue?

Its simply as I stated. I can drive the car forever until I connect that bov hose. Once I do that it idles low, almost stalls and gets jerky or cranks and shuts off immediately.
