i just took mine around a turn and a half clockwise and as far as i understand it regulates your fuel pressures in low boost conditions like around town

if you mess with the AFC take it off and tune it with air for the max amount of boost you make.

Quick update on this it didn't mess with the egts much but as you allow the fuel pin more travel it raises the pump pressure mine is starting to push out the front seal and leaking a little diesel
