Long trips? I told the tech I live right next to the interstate and happens within 10mins on the interstate on the right incline.
I'm just passing the message along, that is all. Not to say I know the guy but fight sound like he was BSing

They put new intercoolers in the 6.4...from what I read I thought that fixed the problem?
EDIT: Went back and did some more reading, I guess there were some guys saying they were still having issues after the IC was replaced. It did take Ford nearly 2 years to come up with the intercooler replacement on the 6.4's, so we are right on track with that
If Ford is gonna do it, hope they hurry up and do it before Winter so I can see if it works or not.

Just a wild theory but is it possible that Ford is using a "refrigeration" technique with the F150 EcoBoost to cool the charge air below OAT? Pressurize the incoming airflow and then cool it back down to OAT as it flows through a highly RESTRICTIVE CAC.
The pressure drop as the cooled airflow exits into the CAC end cap....and thus exposed to whatever level of engine intake vacuum is present, results in the airflow mass declining below its dewpoint.
So it isn't a matter of coming up with just a new CAC design.......

That is a wild "theory"...
Refrigeration? Seriously?

FYI, simply reducing the pressure of air doesn't lower it's temperature. Enthalpy in gases is a function of temperature. If it doesn't do work (i.e. through a turbine), then the enthalpy doesn't change, therefore the temperature doesn't change either.
However, if you drop the presure of a liquid and it goes through a phase change to gas, then the temperature drops. THIS is refrigeration.
Edit: You would have to compress air up to 1000+ psi, then cool it all the way back down to ambient temperature to achieve any "refrigeration" at all.

Um, refrigeration doesn't work that way. I think you just broke two laws of Thermodynamics.

Compressing air results in raising the temperature of that air. Now if you cool the air back down to OAT before releasing it back into the atmosphere....what happens...COLD airflow at the release point, point of high to low pressure transition, plus drips of water.
I guess my compressor/tank violates those rules constantly, elsewhy must I remember to drain the condensate from the tank, factory petcock provided, on a regular basis.
Think about what the effect on FE if you could cruise along using "2" atmospheres of pressure upstream of the throttle plate.
