Does anyone have a accurate fuel mileage reading display?
Mines seems to be off by a couple MPG.

Mine was almost dead on when I was running the 35s without recalibrating the speedo. When I went back to the stock tires I was pleasantly surprised to find that it was reading about two points lower than actual. I'm back into some 285s and am currently going through a tank to see how far off it is now....
