I have both codes on my 06. Truck only builds about 20 pounds of boost. I have an xzt box on too. Wondering if the wires could be damp and causing it? My cel comes on about once a month or a little more lately and today is the first time I pulled the codes. It is also the first time I noticed the lower boost but possible I never noticed before. Any ideas?

 

Light is still on and codes are still there and boost is now normal. I think the connectors must need to be greased?
