Intake mani to TGV is a gasket, as is TGV to intake ports on the head.
Fuel injector seat o-rings are another possible leak spot.
BPV could be leaking by back into inlet

Exhaust leak pre-turbo would be screeching LOUD. Banshee wail / whistling sound.
Not screeching = intake tract.

You need to pressurize the intake tract. Not going to find boost leaks easy without pressure and / or smoke.
