Strange Issue........
Strange Issue........ ...Well yeah, this may seem dumb to some of you but I find it to be an issue. My odometer, I believe, is adding more miles than I am actually traveling and its obviously causing a decrease in the value of my T/A. I've tested it compared to other cars and mine always records more than theirs. For example, my older bro's 02 Mustang GT recorded 5.6 miles on a trip and mine recorded 6.3 which extended over a longer trip would make a big difference due to it being off by that high of a percentage. How would I go about fixing this? Its getting obscene that I live in suburbs and never leave the limits of them and I travel more than "100 miles" a week. Also, this completely throws off my gas mileage calculations which scares the crap out of me because as it stands I am barely getting 16 mpg driving like a granny with these pumped up mileage numbers.

It's probably one of these issues:
- Someone re-tuned for a different tire size or gears that are no longer on the car without setting the PCM back to stock.
- Someone changed the gears and didn't re-tune.
- Someone changed the tire size and didn't re-tune.

Thank you all for your informative responses. I'm at 68mph at 2000RPMs so rear-gears isn't the issue. So, I assume someone had larger tires on it and got it calibrated for them...than neglected to tune back before I got it.
Thanks again.
Thanks again.

My GPS receiver works great for this kind of stuff. Almost every vehicle I've ever used it in was a little bit off. A truck I drove at work had the wrong size tires on it, when the speedometer read 62 mph it was going 65.
