Ok that still doesn't mean it's working correctly... You never answered on how tight u have the star wheel? How about the smoke screw ever adjust that? Hook up compressed air to the boost ref port on the afc housing to see if it actually moves the foot. The looser the starwheel the sooner the rack travels allowing full fueling sooner.

Shouldn't be noisey, AirDog made their setup so it wouldn't be. After I installed mine I had to get outa the truck and crawl under to make sure it was running! All of these parts were brand new?

when there noisey like that it normally means there is air in the system somewhere

Have you changed the filter lately it could be staving the pump for fuel. Pressure and flow do not go hand in hand.

the pressure bounces back an fourth from 50 to 40. the airdog is brand new!!! and the filters have been changed but did look clean when pulled off. it acts like it never has a load on it when you turn it on..

and as far as air in the system i just cant see that possible i have bled the system so many times..
