After 35 in tires, speedo, mpg, and odo are off a little. what's the best way to correct this? thanks

There should be someone in your area with a Smarty. They can load a program,then correct your speedo,then unload and reset to stock. The tire correction will remain in an '06-'07 5. 9. Prior years will revert completely to stock. I don't know if the Bank's stuff will affect it.
