Ok, here are the numbers with my 1st full tank since the Gibson, True Flow, and 35's were installed. I went 261miles exactly when the Low Fuel warning came on and I went 1/10 of a mile to the next gas station. It took 20.46gal to refill.

130 miles were on the NJ Turnpike averaging between 65-75mph with 3 adults in the truck and the remainder of the mileage was earned on country/town roads with just me. This puts me at 49% hwy and 51% city driving.

The magic # is 12.75 MPG on average so far. We'll see if it gets any better.

note: this is on 89 octane

Those numbers look about spot on with 35's. I was down to about 10 mpg's on my 06 before I read a post on fuel injecters causing lower fuel milage. Sure enough. Added some injector cleaner a tank and a half ago and my fuel mileage is about 13 - 14 now. I have been buring corn gas here in the midwest and switched back to good ole 87 oct, Not sure if it was the gas but Im fer sure getting better mileage now.
