again i must defer you to sam unit, aka colin. he is familiar with a problem that can be cured as he says, if your codes support his suggestion then i am sure he has it right.
having said that, the fact you are getting underboost and back pressure do suggest a blocked cat or dpf, which can not be fixed with a sofware update and a differential sensor.
hopefully colin will get back on to help with this one, but i think he is too busy enjoying his 'new' car at the minute!!
