Re: Help me get better fuel mileage
A 1 ton dually with a 454 is not going to get good mileage. It is a big, heavy truck designed to work. A fresh set of plugs and wires may help. A performance tune may help in the power area but not increase mileage. 4:11 gears are fairly steep but required for pulling power. A taller rear tire will make a small difference in ratio that may not yield any increase in mileage.
A few things that will make a difference are:
Front end alignment
Fresh tune up
Max air pressure in the tires
Remove any unnecessary weight
Wash and wax dont' hurt either
And slow down, 65 or less
