Superchips flashpack
 

I'm sorry to say I'm trading in my jeep this weekend, anyway my question is how do I unlock my Flashpack so I could sell it. I set back to stock but it still says linked to my vin#

You have to make sure the tune is back to stock and any advance options you changed. Double check tire pressure settings or other advanced options like that. Check those and return to stock and then you should be good to go.
