not getting enough lift...

well i finally got my truck off the jack stands. But the front is not getting enough lift. its only lifting it about 4 inches or so. my bags are rs62s and its an f150. now i know i dont need a bigger bag because there are other people with the same setup that are getting much more lift.

so what can i do, my compressor is shutting off at 130 psi, is that right??
