You go about this by pressurizing the intake tract and listening for boost leaks. Do a search on twinturbo.net and you will find instructions on how to make a fitting for use with a air compressor to find leaks.

You can make a boost leak plug with a PVC 3" plug put a pressure gage in it along with the air connector add air to 10lbs and listen .. You'll be amazed and where you here the air coming out.
