That should be enough as it doesnt sound like the check will be able to determine if the car was historically reprogrammed (like a flash counter), but just that it has programming from the approved list when tested.
EDIT: The other thing worth nothing is that this would be a major concern if you have a upgraded HPFP that requires the flash option to function properly because you would likely be in a catch 22 situation, unable to flash back to stock even temporarily. "
Basically, CA can now detect if your DME has been remapped and it's an automatic referal to State Ref if you fail.

Correct, you need OEM software on the DME to pass in California:

I don't know for sure if other states have followed. I thought
FastF30 passed on NY while still tuned, but perhaps he can confirm. NY and the tri state area are fairly closed behind CA in terms of regs, but still more lenient. I would just do research for NC specifcally.
