A Buddy suggested it’s a boost leak, the engine is cutting power because it’s not receiving all the boost the turbo is producing, so the car slows down instead of blowing up.
We can guess all we want until we get datalogs

No sure how you would theorize that the car would blow up due to a boost leak. It might cause excessively high WGDC but that's about it... you usually get air mass or other codes with a boost leak also, depending on the severity.
