I run the Smarty with the Edge Juice/Attitude.

Since I am towing regularily all summer & I have only a few mods on my truck (& stock turbo),
I keep my Smarty on very low levels and adjust my J/A as needed.

As was mentioned, the J/A adds timing so one has to use the non-timing power levels with the Smarty.

The new Revo tunes are better with the J/A because you now fine tune the injection timing as you like.
Also with the new Revo tunes, you can now run the 30HP level with no timing which was not possible before.

I now run 30HP tune with stock timing (no added timing). Towing, I run the E/A on level 2. Empty J/A on level 3.

The Smarty timing levels are slightly confusing so be careful when choosing. It would actually be nice if Mads would consolidate the Timing/no Timing levels and just let one tune the timing as required.
