I am getting conflicting information about the need to upgrade the ECM if I put an Arlen Ness Big Sucker and Rolling Thunder slip-ons. Some Tech articles state that the 2009 ECM can handle these changes. Additionally, my local dealer said that they don't do ECM "flashes" anymore, and that I would have to purchase a Race Tuner to upgrade my ECM. If anyone has any information, I would greatly appreciate it.
