Re: Fuel Mileage with Edge Evolution on Extreme
Sorry to burst your bubble, but if you do a search on this forum for programmers + mpg, you'll find that some of the programmers trick the sensors to provide the fuel rate that they do. In doing this, it pretty much makes the lie-o-meter overhead useless. I think you'll be lucky to see mpg's in the 17 to 18 range, hand calculated, on the Extreme program.
Also, your signature doesn't show if you have oversize tires or not, but if you run oversize tires, and the pcm hasn't been reprogrammed for the correct tire size, you won't get accurate numbers unless you factor that in to your equation.
Not saying that mpg's in the 20's isn't achievable, just stating that unless you drive 55 to 60 mph, you're going to see the mpg figures that most everyone else with a 7.3l sees.
