The issue is not waste gate related but rather plumbing related. It is also not a problem with medium output engines. High output engines require more precise waste gate control as they are running on the edge of detonation AND pumping more air at higher boost. If the waste gate feed flow is compromised the wastegate may overboost as it is not seeing the pressure/flow that it should.
