This thing is cool as hell

I confirmed that my speedo reads 5 mph fast. I'm depressed at my 0-60 time, but I really haven't pushed it, either. Finally, I love the HUD feature, although it only works at night.

Tom, thats cool. I did not realize how fast my 2275cc was until I lit it up in second gear. You got to go past 5K. I thought I was gonna break something but all was fine; the torque pushing you into the seat is awesome:) Did you also check speed against your GPS?

Very cool app.

There's one called G-tac Free that's fun to play with.

For us non-Apple folks there are also several free GPS Speedometers for the Droid on Android Market.
