No tune change needed. The TOR map is pretty much the only "aftermarket exhaust" map available at the dealer, besides the one for the new Arrow system map. I don't know if the arrow map can be uploaded to out '05 older style ECU.
The dealer does not know how to build a map to suit, he will just upload pre-made maps supplied by Triumph factory. Unless he is running a dyno shop and wants to push Powercommander on you (which in my opinion is overkill for a muffler change).
