Oh, I didn't answer the rest of your question! But, no, I can't think of anything I don't like about the 6.2. One other thing I do like, which is a function of the power increase, is it seldom shifts down on cruise going up hills and such. This is one thing often mentioned as aggravating by people that drive 5.3's.
