Update... did the grille block, 2nd air dam, tonneau & tailgate spoiler and got a consistent 20.2 mpg on my test run. Then went to the Smarty UDC for engine control and got that up to 22.2 on that same run and it is repeatable. I expect that with a 22 mpg on tap doing 65 I should be easily able to get the 20 mpg on the hiway I was shooting for.
Truck still has the 3" lift, 34" tires and a 180* t-stat. I may test further with a hotter t-stat once I get a new radiator (mines leaking)
Thanks to everyone for their input! (greatly appreciated)
