How and Where you drive
You see that how and where you drive is huge. Bigger than an axle change can get you I'd bet. You're saving two gallons every 100 miles. Percentage wise you cannot get that big a gain yet again. I'd go with the 2.73 and go with the auto trans. Most all auto trans lock up fairly soon and they'll give you better response at low speed and very low rpm because the torque converter will let the engine rev a bit. A std trans with a 2.73 would be dog and tough on clutches. When you do the axle swap start with some test cruise runs at say, 55, 60, and 65 mph and you'll be astounded how the higher speeds hurt your mileage especially with a big vehicle like the CV. I'm guessing at 60 mph you can easily do 30mpg day in day out.
