Thanks for the quick reply. I forgot to list my guages - I have Banks EGT and
Boost.
Basically I want to make my truck run better, it runs good now but I want to get the most out of it. I'm especially interested in improving highway driving as much as possible. You know how it is here in MT, anywhere you go pretty much you're looking at 2-3 hours on the road.
I was kinda leaning toward the 100 hp performance myself. I've never heard anyone say "Boy, I wish I had less power."

If I get a tow tune, what's the difference between the 65 and 80 hp?
I'll have to look at the Banks website or Powerstroke forums and see if there's a write up on how to remove the transcommand module if that's an issue or possible issue.
Thanks for your help!
Oh, I live in the Bitterroot Valley.
