I've actually been discussing the same subject here:
viewtopic.php?f=32&t=5166It appears to be possible to change the gear settings with a reprogram by HPTuners (and probably any other tuner if you have the right files). I just sent some info over the HPTuners yesterday, and they are looking into it to see if they can possibly identify the changes that affect gear and tire settings for the 2002-05 models. I'm crossing my fingers...
At the very least, I posted a tune file that is appropriate for 4.10 gears with 31" tires.
