I have always heard to flash it back to stock before leaving it with the dealer as they may decide to "update" your vehicle.But if they do a reflash or update, will that overwrite the tune?
I have heard of people mentioning the tune and leaving the tuner in the dash for dealers that are tune friendly. That way they can revert it if needed.
As with anything nowadays, YMMV.
