how does the smarty jr tunes compare to the smarty regular tunes? say the smarty 60hp tune to the smarty jr tune closest to that? reason why, is iam thinkin of gettin one or the other, and if say the lower settings on the smarty would be the same as the smarty jr tunes, then i would just get the regular smarty...iam mainly would use the #3 60hp tune on the smarty for everyday driving...hoping for some MPG increase.....

I run SW1 with aftermarket injectors and stock torque management. It gained me about 2 mpg. I'm getting right at 20 mpg. My trucks not fully broken in yet either. SW3 will net you some mileage due to timing.

Go for the regular smarty. Its a lot more flexible. Plus I believe the towing tunes that are on the Jr will become available for the regular smarty. They may already be available for all I know.

BTW Jonesborough is about 40 miles from me. I work in Kingsport at the Eastman.
