Just another newbie to the forum here with some of the same questions. Figured I would piggyback on this thread as opposed to starting a new one. My question is more from a fuel mileage standpoint. I don't need the extra power that a programmer can give, but I am looking at getting the best mileage out of a 02 with the Allison that I can. Towing is not done during the winter months. Once spring rolls around I can only guess that the max that I would tow would be around 5k lbs if I end up with the trailer I want. Have to get the race bike to the track somehow!! I am looking for something simple, I don't have time to mess with tunning or trial and error. I am also looking to keep it as cost effective as possible (cheap, but willing to pony up for something that will work noticeably better). Thanks for the help!
