IAT Sensor = Intake TEMPERATURE sensor
MAF = Mass Air Flow Sensor...which delegates and tells the PCM how much air is entering the engine...the IAT will only tell the PCM what temp the air is at.
Also, this isn't a Camaro.
These cars...no matter anyway you slice it, don't gain power from hardly any intake setup...until you are running super small pulleys and you need the flow...because in the long run, Flow > Ambient Air Temps. Also...the factory corrugated tubing in the intake track is awfully restrictive...and in '97-'98, the factory air box they have two, 90* bends. Which is where the gains are really going to be had.
