I've noticed my speedometer is off in my 2004 Tbird. I've been "warned" a few times by the local law enforcement via lights flashed or a finger wagged... and couldn't figure out why. But it did seem I was passing others when I shouldn't have been.

So, I got an app on my phone for MPH and BINGO - it appears I have a 10% variable ABOVE what it shows.

Does anyone else? If so, can I take it somewhere to have it "fixed"?
