Usually turning the adjustment screw out (counterclockwise) lowers the activation pressure, while turning it in (clockwise) raises the activation pressure.

Yeah I wouldn’t go crazy. Maybe one turn out and give it a try.

Going in should raise it since it’s typically a set screw pushing against a spring mechanism.

Josh is Correct turning it in increases flow. Funny last night I was just talking to my tuner about the meth controller which uses a Hobbs switch.
