I never got the code.
The code shows up when the boost goes over 17PSI for more than on sec.
I always kept the boost under 16 PSI with quick spikes to 17.
I used the controller as a minimum boost limiter... Ex. I would set it for 13 PSI, The PCM would controll the highest boost limit(14PSI). This way the computer thought it had control. The problem with this settup is that when you accelerate just a little bit, Boost would go to a spike and then settle to the MBC setting, even when you where just cruising making the car a little jumpy.
