Message A "boost leak" test is performed by pressurizing the intake tract with ~5psi. Look in classifieds for people selling a boost leak tester, or create your own with a PVC plug.

You'll need a compressor to do the test, but it will help isolate any cracked, leaking components that may be allowing unmetered air to enter the engine.
