04.5 cummins problems

Send your warranty card in. They aren't near as forgiving as fass is about not getting it in time or at all lol.
 
Personally that is the first thing I bought. Lift pump gauge trans temp gauge if it's a auto and a boost gauge. And with airdog they aren't too bad as long as you sent in your warren tee card they will help. My air dog locked up the other day they overnited me a new one and it was installed by noon the next day
 
Found the issue. Valve lash was too right on cylinder 1 exhaust and loose on #5 not sure them 2 rockers got switched or what. But it runs great now
 
glad you found the problem. I have a fass and my relay burned out. I drove it that way without the pump running for at least a few months. When I finally realized it wasn't working and fixed it i noticed no difference in driveabiliy or power
