If you have a spare Map sensor try swapping out that...I had some unusual problems that pointed to the DI cassette but evidently it was the MAP sensor beginning to fail. What finally clued me in was the eventual fouling of the plugs from a too rich mixture. This did not immediately happen and I drove with an occasional stumble for about a month and a swap in of five different cassettes. My stumble was not, however, always at WOT. The new/used MAP resolved it. My car has 400K plus miles.
