2010 5.0 V8 wildly different MAF values?

[MellonRover]

Working on the sorta new to me lr4.
While monitoring engine temps, doing cooling work, I added MAF values.
Noticed one bank read ~500g, and another ~1000g. Different brands of MAF's too. Not sure which is bank 1, or 2. One is Denso, one is Delphi.
Should be causing vastly different fueling with 1/2 engine seeing 2x the airflow right?
Anyone seen this before?

Well, some may disagree but I would want matching MAFS.
Are you throwing codes?

Though its for a different engine, its the same principle…
Note the section on “not plausible”.

Both air boxes feed into a single throttle body so both banks will be drawing from the same source.

True, but see ‘how’ the ecm interprets and reacts to such inconsistencies.

Correct,
It is one tb but the ecu will be seeing wrong total volume of incoming air. Either 25% more or less than actual depending on which maf is accurate...no?
Maybe the 02 sensors added, it can figure it out...but still cant be 100%?
