Not the best comparison since Eaton TVS is far more advanced than those old Mooneyhams however they share boost delivery character.

PD blowers in OEMs have had bypass valves for years now. You can easily drive around off boost in a ZR1. Done it many times. Not the most fun but I don't see why the C7Z couldn't hit 16/27mpg ratings from the EPA.
