Isn’t the access port married to the VIN of the truck? I have mine Goosetuned, but don’t recall if that’s the case.If I sell private party i'll sell mine with the Cobb AP and Goose tune. If I end up trading it in, i'm uninstalling the Cobb AP and exhaust and selling those separately (unless the Cobb AP can be re-used on the '21 once warranty expires).
