Two concepts need to be kept in mind. Gas exchange work is a necessary expenditure because the engine is a chemical process. By being able simply to downsize the compressor, the engine avoids some major pumping losses across the intake valve that would occur to get more aggressive in a Miller application with a conventional engine.
