'Truegearhead' has made *SIGNIFICANT* changes to the car since 2020. I'm not sure how often he is on the 986 Forum now, but he updates on another forum regularly here:

This may be redundant, but have you tested with yarn yet? Tape yarn to the hood all over, especially the trailing edge of your extractor hole, and see what it does. It'll give you a lot of information about where your high pressure, low pressure and attached/detached flow areas are.
