We ran into an issue with compressor surge once we went over 17psi. The turbos would freak out and boost would drop. They are just not happy at this much boost and this low of airflow. I will post up a pic of the map, the + mark is where we are on the map. To fix this I modified one of the bov to push open with boost but not too far open and let some air just vent. This got us past the surge issue and let us bump the boost to get a new best et. This run was at 22psi.
