PID tuning implies the setting/ configuration change required to make so that our feedback system is 100% accurate . in practical cases it will attain max of 80% accuracy .

it is nothing but changing the values of kp ki kd so that our system is linear/properly responding .
the values are theroetically calculated using trial and error method .
