if you make the tune file based on the file pulled from your PCM, it’s not detectable over OBD2. At least with hptuners the CALIDs won’t change. This applies to at least up to 2001 C5. Does not work...

Does the C5 PCM even report the CVNs over OBD2?

HP Tuners shows the CVNs changing when anything in the calibration tables is touched. But when I read the PCM with Tech-2, it only shows CALIDs, which don't change with the tune.
Do these pre-2005...

Ambient 85 degrees, and IAT not much higher. I direct cold air from the fog light screens to the air box. The logging run had no idling, where the IAT climbs quite bad.
