When logging with SCT.. there's only 1 IAT sensor reading.. Is this BEFORE the blower, or AFTER?

I figured there would be a IAT1 and IAT2 reading, but there's not.

SCT Livelink data logging software has inlet and downstream air temp PIDs
 
This is dependent on what ECU and strategy the vehicle has, but iirc off the top of my head:

Inlet Air Temp = IAT1 (sometimes Air Charge Temp) BEFORE blower.

Downstream Air Temp = IAT2 (or Downstream Air Charge Temp) AFTER blower.

Both should be under the enviroment section, again iirc lol. Haven't logged any trucks in a month or two now. FFS
 
IAT1 temp reading should be coming from that sensor you have in your airbox or what you installed in your aftermarket cone filter.
