I wouldn't be surprised if that were happening here if measured temps only rise that much.

Great point^^^^^
I forgot he is probably using a "blow through" MAF with the IAT sensor built in (a guess). Those are very slow reacting.
I'm used to using the "bulb"/stand alone style sensors (PD blower applications) which are nearly instantaneous. I'm mostly using OEM stuff reading through the OEM ECU. I did have some issue with wonky reading on our 2015 Mustang GT sensor so I put a second/stand along gauge to verify what I was seeing (end up the ECU was wrong). I used this one here:
Prosport Intake air temperature gauge, instant read air temperature gauge.
Inexpensive and almost instantaneous. And as far as I can tell very accurate (I rane a few tests on it). They also have one for turbo cars that has two sensors/readouts so you can do a pre and post IC measurement.
