Like others have said, the system pumps air in until the P38 reaches a certain height. The height sensors are what tell the compressor to turn on and off based on height, not pressure. That is how it gives you a level vehicle. When I have operated manually, I measure from the center of the wheel to the fender lip to make things even on both sides. I think the heights are listed on the main site. The way that the airbags roll over themselves creates a situation where more air expands the bag, increasing the height of the car and volume of the bag. This gives you a raised body without increasing the psi much thus preserving the ride at off roads heights. This hits on why the EAS is a great idea, the ability to raise the vehicle without significantly changing the spring rate. This simply isn't possible on with a leaf or coil spring. Its hard to fault the concept.
