It's pretty clear that Motolab's use of the word "tune" is much narrower than other dudes' in this thread.
To generalize a little further, I think a lot of DR dudes are just happy with a bike that runs smoother than stock and subjectively seems faster.
For myself, I like to see posted dyno charts with thorough explanations of the set-up and tune that made them. That helps me make what I believe to be more informed purchases. However I probably won't ever be dyno'ing my personal ride, so strictly speaking, won't ever have an optimally-tuned bike.
Keep at it boys!
