did you adjust the speedo at all using the tire size adjustment? do you have the same wheels/tires that came factory or are they larger?

I have the stock 20 in on them still I did enter my tire size, is there a speedo adjustment in the INTUNE?

The important thing is actually the outer diameter of the tire (measured from the pavement to the top of the rubber), not the wheel size. However, if you have the factory size tires on your vehicle, there is no need to enter that value. The best thing to do at this point would be to open the Quick Adjust menu under Tune Vehicle / Write Vehicle and restore it.

Awesome thank you!!!
