Default 2005 Legacy GT noise while boosting

I have a noise while boosting in every gear and i have no idea wheres its at. I have no lose in power and my turbo is in perfect shape. When i hit around 5 psi and on i can hear a noise kinda sounding like a jack brake on a big rig like somthings sucking for air. I still hit peak boost but have no idea what it is any ideas?
