As for tuning by no load amp draw the numbers are not very useful. Perhaps if we were all drag racing where the throttle goes from 0-100% to the end of the run, or perhaps oval racing where the average RPM is higher, the number might be somewhat useful. But even with oval racing you'd be better off using an inertia dyno that measures torque under load.

With off-road and especially on-road cars the average RPM of an entire lap is not at Max RPM. I would gather to say that 95% of most folks racing off-road and on-road have their motors over timed and would benefit from lower timing bringing the max torque at an RPM range more within the window of their lap. It would require a gearing change since at the lower timing the KV would be less, but with more torque in the right RPM range the motor will pull more gear and likely produce less heat and be more efficient.
