Wow, you guys are making me think about doing a SAS now...
As for 20+ MPG with lower gears, I suppose that might be possible. Lower gears = Lower RPM = Better MPG at a given speed, compared to stock. BUT 35" tires are very big and heavy and would work the engine harder, so if the engine were stock, I wouldn't expect much of an improvement in gas mileage. I would probably expect it to be worse.
You also have to wonder how he is getting his numbers and whether the speedo/odo was properly recalibrated. Does anyone know for certain that he was running 5.38 gears?
