Have not heard of this issue but it could be the computer doing this IF your truck is unmodified, or it could be with the cold air your not getting a full burn of the fuel. The diesel needs heat generated to fire, so as the speed increases there is a lot of air coming in and the grid heater cannot keep up, so less BTU generated when burning
completely stock. It really was like a rev limiter, but like I said engine temp was normal. On the (little) hills that IL has if i was not paying attention it would kick into lower gear as it should but completely bog down.
