I have an AD2 and it seems as if the lock nut on the adjustment screw isnt doing its job. i have recently set it at 20psi. and a day or 2 later my fuel press. gauge is bottoming out on the gauge. i have a hotrod inj. pump and 150hp injectors. i was wondering if im pulling too much fuel, and thats making the AD2 go crazy. I first realized i was having a problem when it sounded like my truck was loading up when revving it at a buddy. it was choppy going up in RPM. almost like a pulling truck. so i turned the AD2 down and it was fine. But now my fuel press. is back up and its getting choppy again. i can also hear my injectors clacking.
