This is a turbo wastegate solenoid code. My searching has told me that much.

Here's the deal. This is not my truck, best friend doesn't do computers and I'm not a CR guy, trying to help him out. He's got a 2007 5.9, manual trans 4WD truck. He had a leaking exhaust gaskets, so he installed a BD two piece manifold and new gaskets. Ever since he has been getting this code. He's had the code reset twice, and each time the truck would go back to boosting the way it should for a day or so. Then, the same code would come back and when he drives it can tell it's not fully boosting like it should. We're trying to nail this this thing down and figure out.
 
sounds like he pulled the wire for the plug for the wg solenoid when swapping out the mani. either that or doesnt have it fully plugged in.
