You can also have dyno not backing up riding.
Tune pointy so your mixture is perfect. Now take throttles off and put set of flatslides on bike. You will have more power, better throttle response and faster bike. Put it on dyno and your mixture will not look as good as first one.
Just because dyno shows flat mixture across rpm's does not mean your bike will run perfect on track. It is common to end up with on/of switch for throttle.
This graph here shows pretty good map but bike is terrible to ride. It is nice and smooth once you are on throttle but when you go in to corner, downshift couple gear, closed throttle to the apex and than when you get back on there is hesitation. Bike bugs and than you open little more throttle and all sudden you get power kick.


Or this one, why is power curve perfect and mixture bad?
