Boost Control

That is one of the best wastegates ever built, even on cars with 350000km on them they are usually in perfect condition. The only thing that can break on them is the diaphram and that is very uncommon. With your new membrane it will probably offer 15-20 more years of trouble free operation. The wastegate could have better flow but has been used successfully to over 700HP in some applications. It is also a bit heavy and a bit large compared to some aftermarket wastegates.
