Here at work have a 2005 3500 quad cab 4x4 with Edge Juice that stumbles or dies under accel with the the module set on any setting above 2. Seems like not enough fuel. My understanding is that this truck has an in-tank lift/pusher pump. Is there a pusher pump solution other than complete FASS system? Does the in-tank pump need to come out if a FASS or other pusher is installed btwn tank and engine? Any help is appreciated, this truck needs to work hard and right now it's not.
