I wanted to clean up my shift points and get rid of the lag when hitting the gas. This thing achieved both those. 2 is what I like best. That's the towing tune. 3&4 are performance and I think they're just to jerky. 1 is just transmission tuning and works great. But 2 is the sweet spot! I also run E85 all the time. Gained 2 mpg also. The only mod I have installed is an Araid mit with drop in filter. Everything else is stock. Am very satisfied with the programmer and glad I got it.
