... and what about that durashitter aftergarbage CAC. They are notorious for being restrictive as all h#ell and are known for causing turbo and intake issues.

high position is not unusual.. engine is trying to do a rapid warm-up cycle. - Its that turbo chuffing that you described that is an issue. Is the turbo still cuffing a lot?

also want to ensure the program in your ecm matches exactly the truck and engine... and that the turbo matches too. Might have the wrong exhaust impeller in it if someone has replaced the turbo in its past at some point.
