Holy crap. I don't know what I am doing different. If I drive mine say at 90k's (50-55MPH) and keep my foot out of it on the highway I have goten up to 25.8 MPG.
All I have is the cat removed, Performance Muffler, 3" DP and K&N. I did have the Bully chip But I sent it back and am going to get TW chip soon. The Bully chip did set me just over 26 MPG.

Are you sure you are using US gallons. Sometimes Canadians use imperial gallons instead of US gallons. That'll boost the mpg by 20%...
