I've had this set-up for about 5 yrs. The first year it worked great. Since then, It's always adjusting air pressure upward. If the truck is empty and pressure is at 10psi, it will start inflating the bags almost instantly. The passenger side bag is the worst. If towing or loaded. I've seen the monitor say I have 110psi and the pressure is always dancing aroung. Airlift sent me a new monitor and valve bells before the warranty was up. That didn't fix anything. Any Idea's on what the problem might be?
