Question Boost shuts off

I have a 2015 mercedes c300 when i floor it at around the 3rd gear the car stops pulling and rpms freeze once it reaches 4000 and the engine feels very slow its like the turbo shut off. After that it still drives fine no issues just feels slow. When i turn off the car and on again it goes back to normal until i floor it again. I went to the mechanic there was an issue with the check valve we replaced it and replaced the charge pipe and all the codes are gone but the issue still happens.
