Very easy installation. Virtually no information is contained in the packing to let you know the differences between the tow/economy and performance mode. Also there is no adjustment for tire size or other options. For $550.00 there should be more than just two modes. Put in on and went from 16 mpg to 21 instantly with over 19 mpg when towing 5300 lb boat.
