Tow mode there is a lot more power down in the lower rang. The truck is much faster now and I can spin tires left and right. I have yet to really burn them on tow. It raid today and I got stopped at a traffic light try to get moving agin and kept spinning. Like to the point I was like this sucks. It keeps the rpms up around 200-300 higher than stock. I'm sucking gas so fast now.
