I got the Gearhead tune as they had a tune that was good for any gas, and whatever you did with raptor. Now they offer a tow tune and regular tune. It is a pain changing tunes to suit what you are doing for the day, or what gas is available. I want a tune that I can hook on a trailer, hit tow button and go. The truck drives good on gearhead tune. Trans shifting is second to none. If truck is a playtoy then you can mess around changing tunes for the day. Mine is a work truck.
