E67 Airflow/Boost Limits - CTS-V??

[Meister]

I am tuning a CTS-V with a 2.55 upper, 9.0 Lower, intake and it makes about 17psi and it seems that no matter what I am hitting a brick wall around 3900-4100rpm (205-208KPA). I have tried maxing out all airflow tables, boost limit tables based on MAP, temperature, etc.

Anyone run into this? Unless I am missing a table somewhere as this is the highest boost E67 I have done to date...

Boost duty cycle goes to 0 when it happens. It is 100 during the beginning of the run

Paul, could you post a log of it happening?

As a quick and dirty test I lowered MAP scalar's and I can pull well to 5k and it cuts at 200kpa. Doing that got me 1000rpm more. Is there like a 206+ max MAP somewhere we are not seeing

I can mechanically bypass the solenoid and its fine.
