My dealer knows I have it and hasn't threatened me with anything.. Same with others on this forum.... If used properly by a qualified dyno technician or if one of the Tuneboy tunes are downloaded and used, I don't see any problems. None of these tunes come close to pushing the engine outside of its evelope.... For example, the 20050_2 Tuneboy tune is very close to the Triumph 20055 "wide open" tune.. Just opens the secondary butterflies 100% in all gears (big difference in performance) and corrects the speedo.... In fact, if I am not mistaken, it seems non-Tuneboy bikes seem to have more mechanical problems on this site than those with Tuneboy.. (an observation, just an anecdotal observation)
