My 5 star tune did nothing at all for me. The only positive is the towing shift pattern is a lot better.Lighter wheels, tires, skinnier tires, drive in a way conducive to using less gasoline. Other than this tuning, I believe 5 star tuning had a tune that should give some mileage, or at least power back. The problem with this is it'll probably void the warranty. Another option that may help is different fuel, 87 octane without ethanol, although this costs more per gallon. Somewhat difficult to increase the mileage in these things as like you said they're already huge/heavy.
