I recommend reaching out to Pro Tuning Freaks (PTF) tech support; they make Bootmod3. As I recall, you should be able to download their app and use it to see if your DME is unlocked without having to purchase a license. If it's unlocked, PTF may be able to tell you if you can check for and possibly identify an existing tune.

If your car has a DME unlock/tune, then upgrading the software will definitely erase the tune and re-lock the DME. Especially if you don't know what tune is on there now, upgrading the software would at least restore the car to a known state but it would also erase any previous DME tunes or coding. One can never guarantee this but a stock tune shouldn't damage the car, although the downpipe may then throw a CEL that was masked by the previous tune.
