I am thinking about sending my computer in for a commercial tune to increase the mpg's of my truck. I have seached the forum for information on the subject and have not quite found what I need to know. Specifically has anyone:
1. Had commercial tune to increase mpg's?
2. What company did it for you?
3. Are you satisfied with the results?
4. What was the mpg increase?
5. What was the price?
