I think you can get either race mode or lope mode. Race mode is a lot of horsepower and lope mode is basically just to make smoke. They are recreational tunes that you won't use often so its whatever u want more I guess

 

I think I'm going to see if I can get 4. best economy and 5. Best econ with t-brake. We live in the mountains and everywhere you go is hills. On my Dodge I leave the pacbrake on all the time.
