Phil,

I wonder why I get 12 and you get 10. We have almost identical set ups??

I get 10 mpg on a good day, as low as 8.5 mpg on a bad one. If a lifted H2 does much better than that, then you are doing well in my view.

Never had vibration from the front driveshaft, nor the rear for that matter. Driveshaft issues are often like tire balancing issues and often will only resonate at certain speeds, although I wouldn't expect it to be from 80-95 mph. I'd make sure all the bolts are tight too, as they can vibrate lose.

I use a Superchips and lowered the shift points and it drives fine for me. The cruise control would always kick down even when my truck was bone stock and I rarely use it anymore. With the SC programming, it still kicks down on hills, but isn't too bad, but still annoying enough not to use. </div></BLOCKQUOTE>
