Would someone please tell me what psi a da teg is suppose to have cause on my adjustable pressure reg I've got it set @ 45psi, and my a/f meter is telling me that running lean. In fact @idle it doesn't even register at all. I know that you gotta let your o2 sensor heat up, so I did and it still reads nothing. When I drive it the metre stays in the red it only turns yellow when i'm at 70-80mph. I need help!!!
