Well i have decided to get the bike tuned, i cant get the HD street tuner beyond certain self tunes perameters and what i mean i am getting back fire when i roll off the throttle. So this is my dilemma. Due i spend the $300 and let Harley fine tune the street tuner or do i get a new TTS and have a performance shop due it for $879. The bike runs well but i know there is still more there that i am not going to get doing on my own. So what do you think?
