"Purchased the Hypertech to provide additional power in pulling a loaded 20ft. toy hauler travel trailer. Haven't pulled the trailer yet but engine doesn't feel any stronger when taking off. Gas mileage has stayed the same at 15.9. I can only hope for smoother hauling experiences this summer." —Donald F from Bridgeport, MI bought a Hypertech Max Energy Programmer for a 2003 GMC Yukon, 4.8L V8.
