What is my speed? Got 3 readings!

You might also be able to get the dealership to recalibrate the speedometer but I dont know if it would be worth the price or trouble. I know a friend of mine got his truck recalibrated at the dealership(because he wanted to get out of a ticket, if the truck really was off then they would waive the fee).

I'm going to "qualify" something Longshot said - but overall, he's giving you good advice.

The FIRST time you program your vehicle to something better than "stock", there will be NO "previous settings" to load. In fact, if you do that first program the way we recommend, you won't even create a "previous settings" file, because you'll skip the "Custom Options menu" choice.

Then, if you DO elect to use the Custom Options menu the next time you load a tune, there will still be no "previous settings" file to load, even though the choice is there, but you will be creating one.

After this, you probably DO want to "Load Previous Settings" as your first step whenever you use the Custom Options Menu in conjunction with loading a tune.
