everything in the turbo system is within 2 years old, from the air line to the box, the box, stainless line to turbo, turbo, all replaced. its also a recon long block with 125k miles, pretty fresh motor

This update is within the last few months, they do fail without outright saying it's broke. Either this is your issue or your exhaust and boost pressure sensors are failing "in range".

interesting, good to know. Is that a direct from Cummins part? How could I test and check my exhaust and boost pressure sensors?
