While I personally liked the cold version of the lopey idle (definitely not as mean sounding as my GTO, but it did sound like a baby high-perf cam) it is no longer there on my truck. I took it in to be reflashed a couple of weeks ago for the downshifting while in cruise control problem, and the mechanic put in everything they had for my truck. The truck now idles smoothly even first thing in the morning. I would think the 2002 models would already have the latest version of all the software (at least as far as the 2001 models are concerned.)
