There is a fix for the condensation build up in the intercooler!

This is the one I am referring to... I suspect it's simply the transmission programming (as you have surmised). I would bet that the transmission programming was tweaked to get the fuel economy numbers up, probably as one of the last steps before product launch. Basically, marketing getting its grubby hands in there messing up good engineering 
.
FWIW, I have also had the 'fall on its face' rapid misfire happen, but only once, and that was during extended light load in rainy conditions. This is definitely the IC condensation issue.

1. IC condensation - just like you experienced. Rapid, multiple misfires that basically puts the engine in limp mode and triggers CEL.
2. Light load shudder, described by some as "55-65mph shudder" which is do to some other system, possibly transmission programming, poor wastegate control, or a combination of both.

The pictures posted a couple of pages ago with the IC cover on it are no different than my truck, and that is a solution that does not work in my climate.

The effectiveness of the intercooler is a function of the temperature of the cooling airflow. At 0F the intercooler would clearly be more efficient, effective, than at the extreme of 120F. With flat-rating imposed by the control computer the maximum HP generated at the 120F extreme would be the artificially imposed limit all the way down to 0F.
Ford added the shield in order to lower the efficiency of the intercooler and to prevent condensation. That shield would also have a greater and greater adverse effect on the intercooler efficiency as the outside temperature rises, reducing the maximum HP with high cooling air temperature.
So the reason your truck downshifted more often after the TSB is because it is most likely flat-rated, the lower HP that can now be produced at those high temperatures dictates the HP limit all the way down to freezing and below.
Am I reading this correctly, those with the newest intercooler design are still experiencing the condensation problem?

Ok, so is this a ‘newly redesigned’ intercooler or just a ‘new’ intercooler. I find it hard to believe they would include the deflector plate on a new IC design…
