At what IAT should I be worried?

Hi,
Today was a hot day in NYC and I drove the car around. In 94 degree weather, idling and driving in traffic, with the air conditioner on, the IAT on my SCT tuner showed around 170-172 degrees sitting in traffic. Now, when the car moved, it would drop down. If I drove continuously, it would drop to 110's to 120's but in stop and go, driving from one stoplight on one block to another stoplight, on the next block, it was in 140's-150's. The traffic was real heavy. I have a JLT Ram Air Intake with a paper filter and I have the heat shield installed.

I checked the intercooler pump and it was on and the fluid was moving around in the reservoir.

Should I be worried? The car seemed to be running fine and the temps would drop down once the car got moving. At what temp should I start freaking out. By the way, the engine coolant temp stayed rock solid at 200.

Also, in my tune, this is my spark retard for ACT:

You say the IAT was 170. That means air intake temp,......so air through the filter. That is different from IAT2 which is the temp you have to be concerned with.

Wait a second. I didn't know there were 2 readings. Let me check my tuner and come back.

No, with no air going across the HE is gets warm. If it drops like you said everything is fine.
