The turbo bypass valve - the hooter valve - is T'd into the intake tube in front of the transmission. It has a vacuum line that goes back to the intake manifold. There's a 1" or so tube from near the turbo outlet to the BPV, which will open when there's vacuum (from the throttle closing). When the valve opens, pressure is routed out the air filter, and if all is working well you'll hear a 'pssst' if there was enough boost when the throttle slammed closed.
If it doesn't work, the pressurized intake air can stall the turbo, and your engine.
