strange turbo whistle from drivers side

replaced head gasket a few months ago and changed from ATT tune to non turbo tune. since then i have noticed a turbo whistling sound on the drivers side while drivng. It always starts at 7psi. To me it sounds like a vaccum leak that is somehow connected to the turbo, it sounds like its coming from a very small area on the drivers side. The sound increase and decreases as boost goes up and down beginning at 7 psi

Any ideas? thanks
