Is there something I can buy to adjust my odometer? With my lift and tires it's about 6-7 mph off. Thanks for the help.

Not sure. Every time I hook it up the check engine light comes on and the code is the over boost sensor. Which I replaced. As long as it's Unhooked the truck runs good. Will EFILIVE fix the problem?
