Yeah, no codes. When I did the flush I just ran tap water in the degas bottle with the drain plug on the bottom of my radiator off on high idle for 30~ minutes then flushed 3x with distilled water then went in with ELC. I didn't want to flush with restore bc my deltas were fine.
Today I towed back and my temps were dead at 204 ect and 224 eot. Ect would hit 206 for 10-15 seconds after a steep hill but drop right back down with no change in eot.
I have a mod friendly dealer by my house and I've had a few conversations with one of the techs, so I'm going there tomo to talk with him and see if we can push it through warranty. I'm under warranty for another 20k, so hopefully we can get something done. I know there is an issue, I just hope ford will take care of it and not give me the usual "your 20 degree deltas are fine" crap.
Btw, how hard is it to change a 6.4 oil cooler yourself?
