I want to know about the everything functions of the Throttle STOP 9.6 Program.
More than 1600 questions have already been answered here in the TechPowerUp ThrottleStop forum. There are hundreds of YouTube videos available.

If you have any specific questions, ask one question every day. Always try asking Google first.
