I installed the DOC race ST kit on my N54 335xi a few months ago.
I have an issue were whether I'm on JB4 map 1 or 2, the boost targets and hits 17psi.

I have the spring setup in the Tial waste gates at 11.5psi. The car runs fine and double checking the vacuum line routing, seems to be correct with the MAC solenoid.

I need to run the car on JB4 map 1 with waste gate pressure only so I can provide some comparison data logs to my pro tuner. However the data logs between map 1 and 2 are almost identical. I have been running the car on 91 octane.

Any help would be greatly appreciated. Thanks
