Since most people post about their tunes, I thought I would take a minute to post about mine. I drove down to SA on Thursday night so that I could have Allen tune my truck first thing Friday morning. I drove from Dallas and averaged 13.5mpg with my cruise set to 73mph. After the tune I immediately drove back to Dallas and the truck averaged 17.3mpg with the cruise set to 85mph! I ws expecting maybe 2mpg better so I was shocked. The truck runs great and hopefully with more miles on it, it will get even better. The only performance mod on my truck is a K&N replacement filter. This was definately a mod!
