This past weekend I changed the plugs in my 07. What an ordeal that was with 3 broken plugs. I had my battery disconnected for roughly 24 hours as I removed the trucks PCM and the mounting bracket to gain access to the passenger side rear plugs.

It never occurred to me to swap my tune back to stock. That said, I'm tuned to level 2. If I need to return to stock, did the Gryphon save my stock tune while being disconnected from battery power?

Did I screw up or are the stock files stored safely in flash memory that doesn't require juice to maintain?

Thanks
