PCM error codes

When I read the fault codes for the PCM on that won't erase is P064F-00 Unauthorised software/calibration detected.

Is this an indication that the ECU has had 3rd party tuning applied? I am concerned because one of the ways to improve power could be to increase torbo boost pressures. This might explain why a seal in the intercooler circuit has blown.

Less likely but there is an outside chance that it could also cause the intake manifolds to crack which is a known issue.
 A visitor from the dark side, my other vehicle is an is still an EV. Strictly speaking its SWMBO.
