I have had it four weeks now and have some good mileage figures in place.
Before Max.
17.8
18.0
17.5
average total = 17.76

After Max.
19.5
20.3
19.4
average total = 19.72

Looks like about 2 mpg better than before. All figures solo driving to work, about 70 % highway and 30 % city. Thought you might like to know some results. Towing was about 1 mpg better. Smooth, sweet, turn the knob up when you need it, or just leave it up all the time.

Does the duramaximizer work with the cruise control?
