Just put the truck and tune through its paces this past week, 1286 miles towing a 23' trailer with two snowmobiles. Drove all over the Michigan and the UP averaging 17.6 mpg over the entire trip. For comparison I had done the same trip with the stock tune between xmas and new year averaged 15.6 mpg.

Peddle response, gains in HP/Torque were noticed on highway entrance and general traffic negotiation. I expected a little better fuel econ based on previous towing with the same trailer but considering the winter fuel blends and the A to B comparison I am incredibly pleased with this tunes gains over stock!
