This combination works against me because due to gear ratios I am at a mechanical disadvantage. I like the tow tune for stop and go because the extra torque helps to overcome this disadvantage. My tow tune is also written with a pedal position map that is less aggressive than stock (for off road use) so the truck is not as jumpy.

Longshot has just posted a very well written comment about how you should look at tuning.

You have to tell Bill EXACTLY what you are looking for in a tune. And, you cannot assume he will understand when you say something like, "highway economy". I know that seems enough to many people, but it really does not fill in the "picture". For instance, what are the distances driven on the "highway"? Is it an Interstate? Where are you driving and what are the conditions (elevation?, hilly? speed limits?, temperatures?). What does your truck weigh when it's being driven this way? Do you have any mods like a bed cap that change the aerodynamics? Do you need passing performance?

I suspect there are other things that might go into this, but the goal is to put Bill into YOUR "driver's seat" so that he can set things up the way he would if he were you, looking for what YOU want. It's not easy, trying to mind-read a customer wanting custom tunes. Try to remove that obstacle and you'll be happier.
