The Hypertech and Pro Comp programmers take a little more than 20 minutes to install their calibration in the PCM. Bring a magazine, some chips, and a soda; you should not leave the vehicle unattended during programming. And you can't use any of the vehicle electrical features such as the radio, or open a door that would turn on a dome light (this is true for any programmer).
