They can help if your truck doesn't like the factory tune particularly, but usually you get more power at the same mpg.

My old 2500 rclb service bed truck liked running at 2500rpm in 5th vs the 2000rpm in 6th. On the hwy it would do about 1 mpg better since it had the power to heavy truck better. I got between 12.5, and 14 mpg.

You have a 4x4. Did you add aggressive tires or a lift?
What is your factory differential ratios?
Do you have a cross bed tool box?
