Sorry for the simple question. Searching thru older posts I realize that the AC is pretty anemic. I also read that it was improved. I was wondering if the newer 2.5 fixed the problem or if it is still pretty anemic. I also commute about 120 mile round trip to one of our satellite offices. With the AC on full, how much does it decrease the range? Thanks for any insights as I prepare for my custom to get done!
