The new Powerstroke did a good job here. However, with the water cooled intercooler on the PSD, I don't think it would have the same outcome if the outside temps were in the 80's instead of in the 20's.
Intake temps play a huge roll in how much power a diesel engine can sustain and just a 10 degree difference in outside temps can increase/decrease EGT's by as much as 50 degrees causing the engine to pull fuel and power to keep them in check. One of the draw backs of a water cooled intercooler is that they get heat soaked under heavy load for long periods of time because the coolant that is keeping the intercooler cool is also getting hot. This is fine in cold weather, but not so much in hotter weather.
