The dealer installed TOR or aftermarket pipe tune closes the secondary throttle plates more to compensate for the lower restriction exhaust to richen the mixture. Since it does nothing more than further close and restrict the intake, the tune actually reduces overall power. If you have no other plans such as a PCV to richen the fuel mapping, you will need to take the hit and go ahead with the dealer tune so the bike does not run lean. Personally, I would go ahead and do something with the filters such as triples, remove the secondaries and install a PCV along with a GiPro. You might as well get all the power from the bike you can rather than just let the dealer choke it off more just so it sounds good.
But then again, you bought the Touring for comfort rather than power, so just doing the dealer download will keep from having to do anything else to the bike that you might not be prepared for or want. It all comes down to what you want it to do ....
