I am just noticing something (a little slow on the uptake). It seems that, while flying red at least, my engine has much less of a tendency to overheat quite so quickly? Where I used to find it necessary to keep it wide open at all times in order to avoid blowing the engine, I now find that I can close it a bit as long as I keep an eye on my oil temps. Is this a new bug fix that I somehow didn't notice in the readme for 4.5? If so, well done TFS!
