Safe setting
I tow a 7000# travel trailer. I had the edge system on level 3 most of the time. I was careful on acceleration from a stop because the tranny pounded pretty hard from first to second if I was under hard pedal. I have now installed a hypertech on stage three. I have seen a good 2/3 mpg increase over the edge but have not towed with it yet.
