Use the standard issue (drag-race to the stop sign) nut behind the wheel and compare smaller to larger engine, the larger engine might win out on FE by virtue of the ECU not having to spend 90% of the time in non-stoichiometric fuel enrichment.

Install an ecomodder/ecodriver nut behind the wheel of the car and compare smaller to larger engine and the smaller engine probably wins every time.
