It would be best to check the pressure under load (and rpm) with fuel gauge taped to the window and driving to rule some things out. At this point though, if you know there has been an update exactly for this problem and the update wasn't done, then maybe lean towards that as well.

I had the fuel pressure gage connected to the service port on the fuel rail and held up by mechanic's wire so I could see it through the windshield, just doing deep stabs of the throttle at idle. Not ideal from a diagnostic perspective but I wouldn't feel safe driving around like this.
