I doubt that this was a piggyback. As if the engine boosts 20 psi the piggy back tells the ECU it is only doing 15 psi > without knowing the "real" psi how can the ecu record it?
Somehow the story sounds familiar. The 2nd owner updated the ECU (either for a recall or something was not right) and then complained afterwards to the dealer that the car isn't as fast as it was before > then it was discovered after someone looked into it in detail.
BTW I wonder how long logs like this are being stored (as you only have so much memory to store values).
