Mike -
Updating both firmware and calibrations WILL return your custom tune to the "canned" version. But, since you are working with a monochrome Gryphon (not a CS/CTS unit), you can easily restore your custom tune.
Just go ahead and allow the firmware and calibration updates to complete. Then, select [Updates]->[Custom File Download] (or [Updates]->[Targeted Functions] depending on the version of Pegasus you are using. That will restore your custom tune and you should be good to go.
