I agree this is a turbo-normalised engine and does not us the turbo to increase power, just correct for altitude and compensate for a little intake pressure drop. With an automatic waste gate, no danger of over boost.
This can be done to almost any engine with no internal changes best with an intercooler after the turbo to cool the compressed air and keep cylinder head temperatures down.
Believe the there are many STC to fit these in GA aircraft in the US.
