Quoting GSX_TC:
on the way to the Shootout this year, going cross country the best i got was 29.16 going through texas. thats with a/c off windows slightly cracked, off boost, and hot weather. Mods are EVO III 16g, 1g Rods, 2G pistons, Evo 8 Fuel pump, Full 3" Exhaust
At what speed were you traveling at? I feel like I don't get much better fuel mileage when I'm on the 1 hr freeway drive to family, but I cruise at 80mph.
