Think I Figured Somthing Out.....AIRMATIC
I'm a little confused on what your asking, so please explain a bit. The car does indeed drop a bit when you shut it down. That is simply to not stress the valves that hold the pressure. The car will lift back up when you hit the button to unlock the car and goes to ride level when the car is cranked. The pressure tank is only maintained while the car is on. It does not waste battery to keep the pressure up in the tank when the car is off.
Hope any of this helps.
John
