We just installed a set of Red Shift 527 cams in my neighbors 2010 Electra Glide. Gutted head pipe, free flowing air filter and slip on mufflers. He is looking at the Dynojet Black Power vision, so I see it has the auto tune feature. So my question is, will there be anything else that will need to purchase for the auto tune. Neither one of us have ever used one, so we just want to make sure to get everything needed.
