Backwards. Sucking a vacuum in the intake causes loss in efficiency. Your gasser will see maximum horsepower-hour/btu of fuel when running full throttle at peak torque rpm. Gearing up and using more throttle opening when requiring low power increases mpg in a gas engine more than it does in a diesel. The best reason to drive a diesel like you stole it is to keep it clean of unburned fuel residues.
