Backstory: My nephew bought a tuned truck that didn't come with the tuner.

He got his hands on an Autocal V3 (I have a flashscan) to put it back in stock, but we don't know which OS to put on there.

So, as the title says, can somebody help me with which stock tune I'll need for this truck?

I do have 12632483, but I am unsure if that is correct.

Since I can't link the truck to the V3 with it tuned, can I manually put his vin in the stock tune (via the tuning tool) and flash his truck back to stock?

Hopefully, I explained it correctly.

Thanks!
