The compressor housing has a rubber seal or gasket between backingplate and snailhousing. If that leaks you also lose boost.
It's all in the details.

I don't follow this description because it seems that any rubber attached to the housing is going to melt. What is "backingplate" or "snailhousing"?
Maybe your leak test is pointing to CBV/BOV again? Is the turbo housing cracked?
What are the symptoms now since ECT replaced?
