Yea program review is your next step. Temp sensor reading 72 deg. All the time is quite suspect of a bad demandate.

All 6 injectors are now replaced and my fuel mileage has come up to running in the high 5’s most of the time. It is still sluggish on throttle and the turbo seems to lag behind. When I run the engine status monitor it says “defueling due to insufficient oxygen(boost pressure)”. I know it says it will do that under hard acceleration but it will do it about any time you increase the throttle % unless you are deliberately very slow on the movement. It has new filters and a new turbo and actuator. Also a new airflow sensor and exhaust gas pressure sensor. The OEM ambient temp sensor reads 72° all the time but the intake temp seems to read correctly. Also, my fuel flow jumps around a lot. At idle it will jump from .8gph to 2gph and it will jump 5+gph while pulling. Any ideas or is that another bad sensor?
I finally got ahold of a Cummins inline6 adapter kit. I’m still learning how to run the insite program and I need guidance on how to pull the programming to send it to Rawze for review? And where to send it Mr Rawze?
Thanks all!! I really appreciate your help and knowledge!

There are no sensors that do that directly or indirectly.
Just about every engine sensor can effect how it performs. The most relevant usually being the exhaust gas (back-pressure) sensor, the IMAP sensor, etc. etc.
Your descriptions point towards some kind of severe neglect of the engine sensors and systems in its past. This is usually coupled with a lot of mechanical neglect too.
also might want to do an overhead valve adjustment and injector leak tests too...
