With 3.73 gears I get an honest 28mpg if I keep the car under 75 mph. In mixed driving I see between 23-25mpg. I can do much worse but that is when I'm really having fun. Which will be your problem too. 3.73s are probably the single best mod for this car short of FI. If you have an automatic, you may want to consider 4.10s but your MPGs will probably be south of 25mpgs.

you're correct, but this works backwards, 2.73 gears have longer gears than 3.73, the car accelerates much faster with 3.73 because the gears are much shorter hence losing out on top speed as well, so cruising at 70mph on 3.73 will be a higher rpm than 2.73 hence loss in MPGs.
I get 24.5 mpgs cruising at 80-90 mph with 3.31s, 26+ at 60-70.

Well I do plan on ordering the Bama tunes this month so ill have a tuner handy. Another thing I'm noticing is that the rear diff is said to be different than the other years in that a new bearing set is needed when installing new gears. I got a set of 3.31s. Dad forgot he had his 07 GT 500 gears removed when he got it Super Snaked. So I'm going to use those.
