Hi I brought a starlet gt the other day and I was told by the person that sold it to me that it was all set up to boost at .9 my problem is it wont hold .9 it over boosts to 1bar up to 1.2bar and nothing will control it first tried was the profec b by turning everything down no difference still over boost then disconnected profec b so we could go back to stock boost settings still over boosting, then an adjustable actuator was fitted tried on a few different settings same thing was happening........anyone got any ideas that we could try would be much appreciated.....
