Has anyone figured out what the screw on the Arctic Blast's Pressure Relief Valve actually does? most guides related to disabling it just have the hole completely plugged with the screw removed, but does making the screw go in/out further change anything?

If I remember correctly, turning the screw in or out adjusts when the PRV activates.

Neato. Do we know which direction does what? (Ex. In = later activation, out = sooner activation or vice versa?)
