probably not your issue but for anyone who comes through..if you're experiencing boost sputter it could be incorrect spark plug gaps. i went to a shop to get valve covers fixed and i left with a sputter when i entered boost. it took me a while to find the cause bc i thought it was a boost leak somewhere.. while i had things apart i decided to check my gaps and to my surprise all of my spark plugs had magically changed to oem gaps (someone at the shop ). i brought them back to FI specs and the sputter went away.
