I spoke with the dealer on this today, and the sales guy called the regional sales manager. He assured me the 2013 was not tamper proof - only the Tiger series has that feature - but was told the ECU will indicate what tampering has been done. Thus, unless an authorized dealer changes the tune to one of only a couple Triumph authorized tunes, one risks voiding any warranty. I'm won't 100% certain this is correct, however, until someone here tries to do it and reports the results.
