I didnt dyno tune but I did do dyno runs before and after applying map changes from auto-tuning on my FP3 and saw definite improvement where the curves smoothed out, and also gained a few digits on both HP and torque lines. Would dyno tuning perfect my map better than the FP3? Maybe, or even probably, but at $500 per session for dyno tuning and possible future mods in mind I'm happy with my FP3.
In my opinion, the only way improving your tune or map is going to be "bad" on the motor is that you're going to run it harder than you otherwise might, both during the tune and probably afterwards as you ride it. Whether you're tuning or just doing a dyno run they're going to run it at higher RPM than you might, all the way to the rev limiter, and once you have improved it you are probably going to want to explore and play with your "new" motor.
