Howdy fellow HD owners, My name is Ken and just traded my '11 FLHX for a '13 Limited. Should have made that decision the first time around. Question, I bought a set of Big Louie's and slipped the bad boys on as soon as the bike was dropped off. I will be putting on the open air box, Do I have to buy the tuner, or can I just get the $190 Stage 1 DL from Harley? I have been getting different feed back, just want to see if can avoid the $400 tuner for now because next year I might get a set of S&S cams, clean up the heads and get the true duals which will require me to get a race tuner. Thanks guys!!!
