I have a 2011 Heritage and I want to put an HD tuner on it. Should I go with the Street or Pro? I have Vance and Hines Straight Shots on the bike now and I will need to upgrade the air filter assembly also to get away from the occasional back fire and better performance. I am sure this question has been asked before but any suggestions on which HD tuner and HD air filter assembly for this bike would be appreciated. Safe Travels!
