My personal truck, 2002 LB7, stock injectors, stock LB7 CP3, AirDog DF-165 Adj, dynoed at 546/1076 at the wheels.
AirDog started acting up on me recently. Lift pump gauge would start creeping up from the normal 13 or so to as high as 30! on the gauge, flick the high beams (don't ask how I figured that out) and it would drop back to normal.
So my assumption was ground issue. Checked/cleaned all the power & ground leads, verified operation. Carry on. Same thing.
Order a replacement motor for it, remove the assy from the frame, clean it all up, swap motors, put it back together and problem solved.
HOWEVER
It was sitting at 14psi and I had an odd surge, only at idle, in gear, rail pressure would move 1000ish psi.
Backed it off to 12psi, problem appears to be solved. Idle rail psi in gear is approx 6000 on the gauge.
