    A programmer may help, indeed. The 5.3 AFM trucks can get up to about 22 MPG highway in stock trim, which would be almost a 50% gain over what you're getting now. If it's not an option, then it's not an option, but it's worth mentioning if you're looking for MPG. Hopefully you can squeeze a few more out of your truck as-is. :)
