Considering closed loop maps (i.e. cruising or low throttle), I don't really see a reason why a turbo kit would decrease MPG. The car is just trimming itself to 14.7 AFR, and beyond that, a tune that controlled open loop (WOT) behavior wouldn't really be beneficial, would it? As long as the car is able to steadily maintain it's target stoich. AFR, the turbocharger setup should increase efficiency.

Even though they are restrictions, per se. Of course, maybe I'm just speculating. :P
