Repo truck tuned and def deleted

I am looking to buy a repo 2016 2500hd. My question about the tune thats in the truck is since i have no idea what it is am i better off buying a new tuner and doing it myself? The other question that would follow that is if i “tune” it will it work correctly since there is no stock tune for the new one to store. Where i live i am not worried about any inspections.

I would get a new tune so you know what you're running in your truck. You can flash right over the current tune with your new tunes. You don't need to worry about the stock tune since the truck is deleted. The stock tune would be worthless unless you were to put everything back to factory, but by the sounds of it you're not interested in doing that

You are correct about me not wanting to back to stock. At this point i think it would be to expensive. The exhaust has been hacked to s&@t for one thing. I will replace it with a complete after market setup. So what is there for a selectable tune? My father has a 5 position switch in his cummins that seems to work very well, even though we mainly use setting 2, the other settings are nice to have

Yes, and yes.

For all you know its loaded with a 200HP tune, i would get something else loaded on it, no you do not need the factory tune to flash, you can flash a delete tune over a delete tune without issue.

and that 200 HP tune can harm your transmission very easily costing you around $4000 to repair.
