A few years ago I replaced the fuel pump and that didn't change anything either but what I did notice was the fuel gauge reading would change. I used to get about 200 miles or more at half tank and now I'm lucky to get 175. At empty, i am lucky to get 290-300 when i used to get 325-335. What could be the problem?
As far as the Gryphon, I use my truck as a daily driver and I want throttle response and fuel economy. I rarely tow but if I do it's about 2500 lbs. or less. I never have a need to race it since its lifted with 35" tires. With that being said, what tunes should be purchased with a Gryphon?

When you lifted the truck and put the big rubbers on is that when you noticed the decrease in mpg's?
Big tires=-mpgs
Regearing can get some of the mpgs back, but not all of them.
What the gearing on the truck now?
And definately a custom tune will help.
