No problem, we all learn here. Yes, what you should do is when the TB is off, take the setscrew out and reinstall from the top. That way you can adjust it easily...reaching underneath is a pain.....

Here is the log with MAP and STIT

Here is the file that is loaded and I made a huge adjustment last night to the VE which is allowing it to idle. Also here is the log from just now idleing only, same log name as other but different.
That can't be right for the VE...way too high. But lets go with it for now.
Using the set screw, open the blade until you have an IAC position count of 50-70. Turn slowly and let the PCM catch up. Shut off engine, disconnect IAC/TPS connector from Throttlebody, turn key on (don't start) for 30 seconds. Then key off and plug IAC/TPS connector back in. This should reset your TPS back to 0% at closed throttle and we will see what the voltage is. I think you will be alright. Want to see it below .75 volts.
Then we will see what the STIT are during idle. They will tell you whether you need to raise or lower your Base Running Airflow values. As it is hot now, run the scan and you can adjust the temp level you are at. Use the delta percentage from what is was and what you changed it to and apply that to all the other temperature cells in the PN row.
The VE is going to then be looked at...it will be way to rich.

Up to temp or does not matter? I know the VE is ridiculous high but funny AFR reads 13.8-15 after adjusting to those numbers.
GM 12615136 is a good choice.

Cranked the screw all the way, slowly, after about half a turn the IAC dropped to 150ish then wouldn't change much from there. Idle dropped way out then slowly with each turn came back.
Disconnected, waited, re-connected and ran log. IAC jumped up 30!!
Try this ...366.70 and 33.33. With Key on and engine off (KOEO) you should see your local baro which down here will be close to 100 kPa or so.

What the ****, really! So should I just apply the three bar OS and go from there?
Not sure where the 366.7 and 33.33 go.
Slow down....you have to get the map straightened out first......:-)
