If you have a Turbotweak tunable prom chip such as the 5.7 version, the chip reverts back to the default settings when the battery is disconnected.
It's a good idea to keep a record of the settings you have changed so you can check them and reset them if needed.

Or, use a Turbotweak tune saver box.............
