I have codes for intake temp sensor voltage on my 2ws cat , I changed the intake temp sensor with another one I had no diff, the truck gradually makes boost but makes 30lbs and holds 30 lbs it's not like my other trucks were it's pretty quick , and yes the waste gate is pinched off and it's a new turbo, I did a injector cut out test and only thing I can come up with is maybe #3 injector
