I think most of the gains they got in mileage is from the gearing. The turbo just let the higher geared car drive more like a normal car. If they can find identical cars one with a turbo and one without there probably wont be any difference.
Adding a turbo to a car and not changing gearing or going to a smaller motor is not going to help anything but acceleration really. Kind of a similar problem of doing aero mods and not changing gearing. The engine load decreases but the rpms are high enough you are still using a lot more gas than you really need to.
