 The pressure is easy to adjust.  There are some small screws on the
 pump.  There is a fine line between minimum pressure for door sealing
 and having the pump cycle.  During flight I get the door seal light
 flickering.  An indication my pressure is too low.

 I just inflated my door seal for the first time and it seems to inflate
 more than necessary.  My door bulged out too.  Did you every reduce your
 pressure?  Just curious how it went.

[Door seal pressure is controlled with the small screw on the pressure switch.]
