I just got my car on the road a few weeks ago and I'm still in the fixing the bugs stage.

My question is on my speedometer. I was driving my car around this weekend with a TomTom that tells you how fast your going to see if I have chosen the correct speedometer gear. At 60 miles an hour on the TomTom I am showing 60 miles an hour on my speeo, but anything slower it shows a bit off and the slower I go the more it's off. I'm not really concerned with the speed as I am with the milage being correct.

Is anyone else experiencing this?

Thanks.
