Engine does not hesitate, but have the maf code. Do I replace or clean?

There's a bulletin about it, ITB19-027:

Basically, if your ECM part number suffix is any of the following on a '15, you take it to the dealer and get the ECM reflashed:
9NE4A, 9NE5A, 9NE6A, 9NE7A, 9NE8A, 9NE9A
9NE4B, 9NE5B, 9NE6B, 9NE7B, 9NE8B, 9NE9B
9NE4C, 9NE5C, 9NE6C, 9NE7C, 9NE8C, 9NE9C
9NE4D, 9NE5D, 9NE6D, 9NE7D, 9NE8D, 9NE9D
9NE4E, 9NE5E, 9NE6E, 9NE7E, 9NE8E, 9NE9E

FYI, P0101 isn't a MAF code per se, it's an induction performance code. It means something isn't making sense on the induction side of the engine, but the ECM can't figure out what.
