Hello I am new to the forum and new to EFI live. I have done some tuning with other platforms but this is my first with EFI live and the LLY. I got some tunes for ATP trucks and they are very nice tunes. The issue is the tranny went into limp mode so I want to flash back to stock for now. The issue is I don't have a stock tune from the truck... Long story. but I purchased the efi live v2 and the tunes all at once so my v2 locked the ecm. I had a buddy try and flash the ECM back to stock using his tech2 but the ecm was locked.

Does anyone have a stock tune I can flash back or what do i need to do so that the dealer can flash back to stock

Thank you for the help
