Number 1: set this table to 100 across the board and test it out. Ill bet this is the majority of the issue

If it still closes after that, but less, open Engine -> General -> Desired Air Load and set the 100% column higher. Its around 110-105 stock, try 150 then 200 and see if that helps. If it does, then smooth that table afterward to not have a steep ledge of DAL at 100%

Your max desired throttle and max airload also appear to be stock. What variants are your car?
