help with diagnosing MAF failure

[bsbllfit7]

hello everyone i am trying to attempt to see if my maf has gone out. I was able to boost fine to 20-21 psi no problem then one day when i went out it begins to boost but then cuts out. Not quite like fuel cut but very similar. It goes out then begins to boost again then goes out again. It wont allow me to post the log since i posted it in alternative thread but i will post the link to that thread, the log in question is the one labeled boost cut log.

sounds more like a boost leak too me. But if you want to have you maf check take it to a dealer and have them test it. the just check the electrical resistance too see if its in spec. They should be able to do this at like an auto zone or something like that.

Uh I don't think its a boost leak. Everything has been checked and there are no large leaks whatsoever. There may be some tiny leaks but its definitely something that is cutting fuel supply or something along those lines
