Default air runner question

just was wondering if this is normal..

in the morning i air up my car to like 100 psi front and 88 psi rear.. i have dakota gauges.. my tank starts to charge and when it reaches 190 psi on the tank, the compressor stops..then my front driver suspension reads 140psi and tank is like 138psi and that strats to see saw.. like suspension goes down to 100psi and tank is 190psi..and goes back up again... after you turn the car off, maybe like lunch time the gauges reads normal.. 100psi front and 88psi rear.

is that normal....

Definitely not normal. I also have air runner but on a 2gs. Wrong readings can damage your suspension. I remember air runner saying 140psi is the max in each bag without damaging them. You should have your air runner checked. Do you just have the kit or do you also have the optional parts that is offered?

sounds like it could be a number of things.. faulty valves, tank sensor, relay, gauge.
