I've read multiple articles about the need to dynotune, in my case a '21 Freewheeler, when you start changing things like intake and exhaust. I did the intake about 11 months back and now I'm waiting for my Cobra 909-Twins slip-ons to be delivered. If I were to get the trike dyontuned what exactly does that do for me other than give me a readout of the fuel/air mixtures at various rpms and such? Does it adjust the fuel/air mixture for peak performance or do I just get a piece of paper showing me where it's at? I re-watched DK Customs vid about the '21 Freewheelers NOT running lean and how swapping out intake and exhaust shouldn't be a problem, but remapping for better fuel/air mix could help. Is that what the dynotune does? Adjust the fuel/air mix to match your setup or just tell you what it is?
