Pop open the engine bay, and turn on the engine. While running, floor the engine by turning the butterfly valve on the intake manifold. Then quickly release it. If you rev it close to redline, it should boost to about 2-3psi and should allow the sound you hear. I know that it only happens under boost, but this may be enough for the sound to reproduce it'self.
How did you clean the wastegate out??
