I found running above 60 you are just wasting fuel with this set up. I know if you run 70 your milage will be knocked down to 17-18 mpg and in my line of work fuel is my biggest expense I have.

Wow...dropping highway speed from 70 to 60 gives you 5-7 MPG better? I'd be after a set of 3.42 gears YESTERDAY.
Thanks for the replies, guys.
