Given the purpose of protecting your no-longer-available tune, do you know someone with HPTuners or equivalent? It does not cost any credits to read and save a tune, but if you need to write it back to the ECU in the future it is $50-$100 in credits for the first time write and unlimited to the same vehicle after that. Might be good insurance.

Edit: I have done that on all my vehicles for the last 20 years. Now have the latest HPTuners. Save the original file, and then any iteration whether dealer reflash or tunes, so I have every variation to write or compare. For example mine has the tune for the supercharger, but I went in and disabled the AFM so it never runs on 4 cylinders, but kept the previous file too and the oem so if I ever remove the supercharger I can easily go back to stock.
