Alpha, that's a good description and assessment, and so far in my experience, there HAS been a fuel efficiency hit. Since I was able to do more highway miles on my last tank of gas, I got a better feel for it as compared to before I had the update done, and my MPG have definitely been worse.
Problem is, it's also been real cold here too, so I can't really say how MUCH of an efficiency hit there is.
