I repeat.... you don't know how to use the tool.
You (we) need more info..... you need to view Freeze Frame Data, or to log certain PIDs to see what's not going as expected..... if you want to actually diagnose anything.
If you just want generic and vague answers, then YES, your boost issue COULD be related to the flaps being messed up.
Watch the training videos, learn how to use the tool. Just showing the code and description is very minimal information. Click on each of them to get more info. Print out\export the diagnostic report to show the rest, etc.
Log your actual vs requested boost parameters.
Perform output tests on your flaps and see if they are completely stuck, or only partially limited.. correct issue by cleaning them, unfreezing them, etc.
Your boost code is intermittent.... so it only happens sometimes.... without more detail, you don't know if this is at certain temps, rpm, elevations, etc.
Details matter.... you don't have any details....
