Stock setting is OK. But you can get more good feelings if you adjust.

The firmware in a 2k servo verifies the position of the servo arm two thousand times each second, while the firmware found in previous servos verify the arm’s position one thousand times per second.This greater number of verifications makes for a very precise servo, and gives it a more “solid” feel.

It is recommended to use a booster cable with 2k servos to ensure steady voltage at all times.
