I think you are better off letting the ecu control boost, but there may be something in particular that precludes you from doing that.
I know I would achieve a smoother boost response & have better control of the boost with out spiking
this becomes more apparent with the more boost you run.
I can easily change the level of boost at will mostly important when you leave the car with the service dept or valet parking. or on the recent HOT days, it is most important to be able to drop the boost at will. you need the confidence that you can put your foot flat to the floor & know that its not going to ping.
