It also makes the car stumble and stall, and since it has to be a STRONG BOV and stay closed under all but the greatest of vaccum conditions, it won't open under low boost, so it'll stuble and make weird noises and cause compressor surge, which kilss a turbo, other then that it is cool.
I ran my car like this for a while, not good, had a HKS SSQBOV, car would stall in stop and goo all day, hit the gas, let off, revs hit the bottom of the rpms and then bounced back. If you run a greddy, it'll be worse, as it will leak under partial throttle.
Vent back into the intake, just a LAW of the car, search here on it at

Not to be done.

My car ran like crap whe I dumped to Atmos. also ran rich between shifts and shot black smoke, unburnt fuel, out the exhaust. also experienced the stumble when coming to a stop rpms would fall almost to the point of stalling them would flutter back up.

Mine always belches fuel. 
The point of VTA is that it reduces compressor surge when shifting.
If the ECU doesn't know where all the air is going then yes, you may have stalling problems, but there are ways around them with the stock ECU (usually through use of piggyback ECU's).
