CM871 Unknown Tune
New here on the forum and need some help/direction on a tune,

I have a Cummins CM871 with around 390k miles on it that was just acquired. It has the dosing injector disconnected and fuel line plugged. Also the DFP wiring is all disconnected. So I know someone has tried to demandate. The engine also idles a bit rough and rpms jump around a bit. I have looked into the cal file on the ECU and it looks like someone has disabled the EGR and DPF. Would anyone have a cal file for a AV10249 that I could compare to my tune to see what has been changed, and any advice to get this truck running with a reliable tune as it doesn't seem like the one that I have has been done right.

I have both Insite and Calterm, and a Nexiq usb-link.
