Turbo charging off topic

I have never been absolutely sure, but I don't think the added power offsets the fuel usage.
So I would have to say the turbo engine will use more fuel per mile than the same engine non turbo.

Maybe if it has real mild boost there could be a point where it offsets, but I have NEVER heard anyone say they get better economy when they installed a turbo.
I have heard many say they used more fuel.
