The Chinese wastegates I have are all measuring smaller than what there marked, the small measurement is from the body inlet and outlet.
A branded tial or turbosmart body has a 44mm inlet and out or a 60mm inlet and outlet . this is independent to the inlet and outlet flange size.
So these Chinese wastegates are sized smaller and flow less. So my "50/60mm" Chinese wastegate flows similar to a 44mm branded.
Look at any branded wastegates website for detailed dimensions and this will tell you the opening dictates the size, not the inlet or outlet flange.
