Default I'm down about 2psi of boost, and car is holding about 17hg at idle as opposed to 20.

I know this possibly points to a boost leak. Any chance a dirty air filter could be associated with the problem, though? I haven't cleaned it in months.

That being said, I'm still peaking at about 21 and holding at 19-20. I want to get back up here, though.

Could be, but it just feels "off."

Default Yeah, I thought that about the boost. It was the hg reading that had me wondering, though.

I don't ever recall being below 20hg at idle.

Default Normal.....20 is actually a little low (or high)

Cheap gauges as well as the "slightest" change in idle RPM's will vary that much..

Default Same here bro! It was 101 on my way into work today and this...

humidity is killing me! If it keeps up let me know and we'll hook my brother's pressure tester up to it. I'd say take it out at night but it's not that much better then either.
