How does this differ from just pushing the power button. Does this simply activate the power all the time? Do you get additional throttle response when you activate the power button with the tune?

Power button does not add more power. It changes the steering and the throttle sensitivity. With ECU tune you can make it more aggressive/sensitive and the power comes from air/fuel ratio modification.
