Maf drop out ignore

[Steve V]

Can somebody explain how it works. I have extender chip, the attached log felt clean but look at the MAF. 3.5 maf with reg trans older version.

Swapped MAF still getting funky readings....see attached log, also have thread in general tech.

TR6 gave me a code 42...so I took it off. These logs are with my stock ignition. No other changes and still a few dropouts. Is this something happening or a software anomaly or interference????
