Maybe, maybe not.  There's the matter of throttling loses in gas engines
-- at small throttle openings, high RPMs, and light loads, the engine ends
up having to draw air through a relatively small opening.  This creates a
partial vacuum in the manifold that takes energy to overcome.  Not
applicable to diesels, of course.
