Adaptations to things like throttle pedals don't make any difference to how hard it runs, as they don't affect power. They simply affect how the pedal responds. I don't see the point of resetting the adaptations. If you want the throttle pedal to respond differently, ie more aggressively, just be more aggressive on the pedal. Yes, you will burn more fuel.

If it runs better because you got it good and hot and cleared it out, then resetting adaptations won't have any affect.
