No problem! you posted your air dog is making 2 psi? Just want to make sure its not a mistype! please confirm

have you looked at actual rail pressure when it its doing it? Have you modified the fuel rail fittings?

he said he has an Air Dog 2 and doesn't know the pressure it is at. It wasn't a mis-type

and rail pressure were all over the place up down then desired went to 0 and rail was going all over the place ? so if it runs fine part of the time what could it be?
