So after months of being a good citizen and driving in stock+ mode with my DuramaxTuner, I decided to kick it up to mode 3, Sport-Economy. Shockingly it does just what it says. A noticeable kick in the pants with no discernible loss in fuel economy. I got blown away by a V8 Jeep Grand Cherokee in Stock+ Mode and said "Never Again!".
