2014 full delete Efi Live single tow tune only. (No monitor)

I continue to get a lope or surge at idle. We replaced the fuel regulator (FCA) and filters. This didn’t help. When I reflash the tune with the autocal, it has normal idle again. But this doesn’t last. It starts the lope again and has to be reflashed again to make it idle normally.

My tuner is confused. Any ideas why this would occur? I have a video under 4th gen common rail. “Lope at idle”.

Sorry don’t know how to import it to this forum.
