Power mpgs and monitoring whats happening in the truck. I noticed almost 2mpgs difference and i love the shift firmness and shift point adjustments. Plus more power sent from area 51
i love it, i just want a new color display one hahaha. its all in how you tune it. its got 3 custom settings but you can adjust all settings and create your own tune. im not sure if you can buy tunes for this one though.
