Yes, while that may be the case, the manufacturer still runs more aggressive tunes and lower compression on turbocharged engines. It's a fact of life.

When I had the turbo on my insight, my MPG went up by 3mpg. This was measured at the pump, not going off the FCD.

Why are we still beating this over the head anyway, it's been proven when you add a properly sized turbo/supercharger to an N/A engine, it gains 10-20% MPG due to the increased VE.
