4EAT tranny - snorkus intake mod

When I drive normally I can here the recirc valve always open at partial throttle until the wastegate opens. (sounds like rushing water almost) When I give it a lot of throttle it'll close and all I hear is the turbo sound, then the quiet blow off pfffttttt when I let off the pedal.

Is this normal for a turbo auto?

To test my theory of air leaking past the recirc valve i pulled the recirc hose and plugged it. When i drove around you could constantly hear air slipping past while the turbo was spooling up but if i stomp on it it seals shut. seems strange to me but maybe i'm :crazy:
