Installed the SCT X4 Power Flash Programmer a week ago. Set it up for towing. Had been using another popular brand of programmer for over 10-years. Very glad that I switched to this SCT X4 unit. Towed my 6900 lb boat and horse trailer with out any problems. Increased my fuel mileage, along with better performance from a Ford F-250 Super Duty diesel 7.3L with over 218,000 miles on it.
