just start yankin on all your piping from the turbo - intercooler - tb...one of them is almost deffinately loose...if you can't find it that way start pullin the couplers off and looking for holes in em.

If it is a lose charge pipe you will definatly "hear" it.

Factory wastegate? could be a broken actuator spring or diaphram depending on how the wastegate is made.

Could also be a problem on the exhaust side of the turbo.

hard to tell without hearing/driving in the car.

sounds like a coupler that is loose or ripped.

but then again tough to tell from limited info.
