A guy I see occasionally at the local Harley dealer rides a 2014 Ultra limited, he is very happy with how it runs. He sees on other forums how much the cost of tuners are and wonders are they worth the money? He asked me with the cost of these tuners being so expensive are they really worth the money, i.e., are you getting much bang for your buck? He doesn't race and generally rides with a few friends when he has the time. He's running a stock pipe but would like something with a little more growl to it. Thoughts??
