    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

    I would look at the wiring harness a bit closer. Do the 10lb pull test on each wire. If that's OK. Remove the ecm plug and load test the circuit with a headlight bulb and wiggle the harness . If you have et you could do the wiggle test with it.
