If the true problem is overpressure (vice a bad sensor), perhaps it is related a faulty pressure relief valve, allowing overboost?
Since the car's performance is unrestrained, it suggests you are getting (at least) full expected pressure in the intake.

If it were me, I'd be rigging in a pressure gage on the boost side to verify actual manifold pressure.
