Actually, his thinking is spot on.

You seem to have trouble understanding how a gasoline engine controls power output. If you are close to atmospheric pressure at the intake manifold, you are either running a NA engine at wide open throttle or a turbo engine at a lower throttle opening combined with boost. The result is high power output, which as he said will result in a much higher speed.

I think the problem may be that you are thinking in terms of engine efficiency, rather than fuel mileage. A turbo engine, running with some boost very well may have a higher "efficiency", the problem is, it also has way higher aero drag because it is pushing the vehicle at a high rate of speed.
