Idle Stays the Same with A/C On
My '03 Silverado runs and idles fine, around 700 rpm. I have cleaned the MAF thoroughly and it has a new ported TB. The only thing I have noticed lately though is that when I turn the A/C on, the idle stays the same. This makes it struggle just a bit at a dead stop, but its barely noticeable. I know when I turn the A/C on the idle is stupposed to go up a little, probably to around 1,000 rpm or just above. What exactly is it that tell the truck to raise the idle for the extra load? Is there a sensor somewhere that could be changed?

Possibly. Its not too bad. If it only is supposed to go up that much then I won't worry about it. The A/C compressor is kind of on its way out anyway which may cause it to be a bit harder to turn.
When you do an idle re-learn, should you wait a certain amount of time before you turn on the A/C when its first started up after the battery has been unplugged? Could that make some difference?
