I can tell you that I do not have a tow tune because I might tow something twice a year so its not worth it.I used my 87 performance tune and towed my buddys 96 f150 4x4 up to the sand dunes on a car trailer with no problems.I was safe with it though and set the gryphon so I could see what gear it was in and whether the torque convertor was locked.I also did not floor board it ever either but was still able to tow 70-75mph going down the highway about 200 miles.I think the weight was around 7,500 pounds I towed.I then unhoocked the trailer,beat the hell out of my truck all day on the sand dunes,then hooked back up to the trailer and towed his truck back home.Thats a Ford for ya.
