The powerful "Monster" performance series from Savox utilize an all aluminum case, unique brushless motor and controller technology to boost power up to 35% over previous generation servos.
The answer to this question is partially dependent on what you are using to control the servo. 
Click for a quick video explanation.
With an Average Radio System:
102°
Your average transmitter and receiver will output a relatively narrow PWM signal range.
Radio System + Travel Tuner:
160°
Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges.
Wide Signal Controllers:
160°
Controllers such as the Servo Commander, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
