Hardest part of installation is running wires and stuff. Bought this tuner after reading reviews on others.Bully Tech support is very helpful! Installed performance tune and drove to work for a week. MPG went from 17 to 20! Installed tow tune and pulled my 5800 lb travel trailer with full water tank.Tow MPG went from 9 to 13 and went faster up the hills with less downshifting! The driving coach takes a few drives to get used to but not a biggie!
