 This is how I tune, it may be wrong, as there are many tuning methods, but this might help or give you some ideas, and note this is just my opinion, its written for acro mode tuning: This is how I tune, it may be wrong, as there are many tuning methods, but this might help or give you some ideas, and note this is just my opinion, its written for acro mode tuning:

 Something else to add is that in general, higher kv motors need less PID because in effect they add gain to the PID's compared to the same size motor with lower kv rating. A similar thing can happen by changing prop pitch/diameter or number of cells, again the tuning is affected because for the same change in motor speed command from the FC, a different thrust change occurs compared to before the props or number of cells was changed. Unfortunately the FC does not know anything about the motors/props/batteries fitted, so it has to be tuned for whatever combination of parts are being used. Sometimes hardware changes do not require a retune, but usually they do. Something else to add is that in general, higher kv motors need less PID because in effect they add gain to the PID's compared to the same size motor with lower kv rating.
