I got around 8 mpg doing 80 mph on a cross country trip but get around 10 mpg in "normal" easy driving: 65 mph.

Short answer... (lol. as if I could actually give a short answer to anything.)
At those speeds and conditions you "probably" will see a "little" better mileage.
I know I put up REALLY LONG posts that are a lot to read, so you probably missed what I said about mileage. Here's the post...

If that doesn't help, let me know. And the difference between power between your '99 and your new V10 being "huge"? The power difference between stock and tuned in that new V10 might not feel as much, but it will absolutely be noticeable. My 27.7 Vegas almost feels "fast" after my tuning and wheel/tire swap. I know that sounds crazy but I've driven a lot of vehicles in my life and it's far from a lumbering beast that most would expect a ~14k lbs 28 foot long box to be.
