Popping noise while in boost

As the title says popping while in boost. Came out of nowhere. See video below. Let me know if you have any questions. Thanks.

Anyone have any thoughts? HPT doesn't show misfire.

I couldn't get the video to come up, but if it sounds like popcorn, it's one of your injector seals.

Oh, wait. Is this on an LNF?
