Good item

Reviewed By Kevin K (Cleveland, AL) —12/13/2014 10:58 AM

Have bought two of these now for a Ford Explorer Sporttrac and a Dodge Ram w/ Hemi. The Ford is used to pull a 3800 lb. camper and it has greatly improved shifting and towing. I did not see much increase in mileage with gas saver mode but can tell a real difference in the power and shifting in Performance Mode. The one for my sons Dodge has not been used enough to rate yet but he does claim son increase in fuel economy on the highway driving the 300 miles between home and college.
