Ethan,Jerry I would have your service guy call the Thousand Oaks CA Service Center and ask the techs what exactly they did. I believe it was something as simple as them exiting the reflash program properly. If you dont exit the reflash program properly the flash wont take. The Thousand Oaks service center phone number is 805-267-3600. Any of the guys in service can help you.
Hope this helps!!!
Thanks. I'll probably call them myself so I understand what to tell them to look for. They won't spend the money at the dealer.
