The French may well be a biker loving country, but that Triumph dealer seems to me to be an arsehole. I'd suggest changing dealers, but (knowing where you are in France) I guess the next one is a bit of distance away from you. How's your French? If its OK, tell him that if he loads that tune on your bike again, you'll tear him a new one.
A jobsworth bureaucratic French Triumph dealers mechanic. Hmmm, is that everyones worst nightmare?
