I'm going to change my gear ratio from a 3.42 to a 4.10 for towing. I have changed the tires from 265/70/17 to285/70/17. I'm looking to corect the speedometer and I can't seem to find a dealer or anyone to do this. So I need to buy a programmer. Which one is best?

Thats bull, any dealer should be able to do this.

 

As for a programmer, I'd go with the Edge Evloution.
