Hrmm, that is interesting then. If the throttle were closed, the car shifted and the revs dropped, boost should have dropped too with a quick spike on the throttle close. But according to your plot the boost held for about a second. The PROcede could not caused this if the throttle was closed. IMO, that would indicate the diverter valves did not open and it took a moment for the compressor surge to finalize.
But to avoid any confusion, I would recheck all connection just to be sure all is fine.
In addition, I would drop the user values down some just to play it conservative for the time and to see if the sound reoccurs. I would also re-log to see if that throttle lift sustained boost is measured again.
