Can anyone tell me why HD customer care and my local HD dealer is telling me that the SE street performance tuner will not work on my 2013 Tri-Glide? I am only going to do a stage one upgrade, air cleaner, power duals, V&H trike deluxe slip-ons. Since this will be the only performance upgrade I intend to do and "can not find anyone in the Houston area" with equipment to dyno my bike why do I need to spend the extra cost for the SE Super tuner? One HD dealer in my area told me that for what I am doing to my bike the flash download would be all that I need.
