I would trust statements like that from an OEM about as far as I can throw my truck.

you need to find out exactly what program that engine sert# calls for. And you also need to find out exactly what program was shoved into your ecm.. and then have a comprehensive comparison done to ensure they are actually 100% compatible.

Has anyone looked at fueling actuators on this?
Check for wet harness on ifsm isolate front 3 cylinders and rear three etc on insite.
Very common and easy for anyone to check.

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".

whats the part # for the upfit kit?

That is a long-block generic ser#. It is not searchable on quickserv to see what program belongs in it. - What is the CPL on the engines current data-plate.. and what is the VIN# for the vehicle?.
