The main reason to cool the wastegate would be to extend the life of the internal parts (diaphragm, valve, etc).
I ordered my dual wastegates when V44 was out but I think around the time of delivery MV-R was out so that's what I've been sent. I didn't complain since it's the "new and improved" product. I didn't pay attention to to details. Anyway no big deal I'll run them non-watercooled.

Yeah I think so too. Just wanted to double check. My mechanic told me he's sold few of those none with watercooling activated.
I'll let you guys know if mine fails due to heat in the long run.
