BOV is BO'ing too much!

I'm getting my 87 Daytona on the road finally (87 T1 converted to 89 blow through no intercooler yet), and have noticed a problem with the BOV. I can hear it start to leak boost as soon as my AutoMeter boost gauge starts reading pressure in the intake. If I keep on it long enough it'll still go to 7-8 psi of boost, and I get that cool BOV sound when I let off the throttle, but it's leaking no matter what.

It's the stock BOV out of the 89 Caravan airbox that gave me the intake assembly.

I hooked up the "IN" line, left the output open, and there's a small hose fitting (1/8") on the other end of the BOV that is currently unhooked because I didn't know where it goes. Maybe that's the problem?

There's no air cleaner assembly AT ALL on the car yet. Just the open turbo inlet.

the vacuum line you mean? on the top? hook that into manifold vacuum/boost source

I did that today. No change. It's T'd in right next to the boost gauge, in the hose that runs from the intake to the power brake booster.
