Here are some logs I took for comparison. This is with a Twin Turbo setup.
In This log IAT starts at 111* and end at 131*. 8:24 PM about 8PSI.
In This log IAT starts at 106* and end at 124*. 8:33 PM about 8PSI.
In This log IAT starts at 113* and end at 136*. 8:44 PM about 8PSI. Hottest of that day.
In This log IAT starts at 93* and end at 120*. 9:44 PM about 8PSI. Coldest of that day after an hour cooldown.
In This log IAT starts at 138* and end at 154*. 2:35 PM about 8-13PSI. I made a run then let it idle and heatsoak in the mid-day heat. I was testing the boost controller so I activated it in 4th but it was surging.
