black smoke under full throttle
So I started to NM from fort worth texas with my 33" camper blew my CAC pipe four times. Finally got there. In the morning it took longer than expected to start. When it did white smoke. That was replaced with black smoke under full throttle. I went from elevation of 700 to 8000 Ft. Should I care about black smoke? Meaning should I take it to Ford and get a rental car to get it looked at for our trip home.
96 degrees towing at 70mph with lots of climbing mountains.

This is a good place to start. Read that and see if it's the same

ECT is high, shouldn't see much over 220 for long, was your fan screening good? EOT very high 3 degrees from defuel. If you drop a gear on the hills, you will move water, more cooling, both coolant and oil. Your boost seems low fir a hill. But I get you think FICM, when warm it should be doing 48 volts easy. Those r high temps, what's the weight of trailer? I wouldn't expect that low boost and those temps, so......
Got a boot leak on there loosing boost, or you have sensor issues with MAF, MAP,, IAT2, or EBP. Consider cleaning all, check map and EBP and I be and run relearn? You should see 26-28 PSI those speeds, hill, temps. FWIW. Hope this helps.

So higher rpm's lower engine temps? Had no idea. I thought the opposite would happen.

Is the clutch fan roaring at those temps? Unless you're blasting music, it will be very obvious if the fan is working as it should.
Black smoke, high temps (probably high egt as well) and low boost all point to a boost leak. Do you have a plastic or metal driver's side CAC tube? If plastic, it's hard to detect when they start leaking at the accordion-looking part.
Btw, defuel starts around 253 oil temp, not 243.

Trailer weighs 10k lbs. My boost level seem to drop when I replaced the idler pulleys and water pump with a bullet proof pump. I didn't touch any of the cac system. I replaced all cac boots with new a few months ago but boost was fine after they were replaced. When I started towing the cac started comin off. Three times at the turbo and once front and center by the thermostat housing. I tightened all of the cacs except the drivers side one. I will do that now and let you know if there is any change.
