Hey guys, good posts.
I've tested with and without screens to determine if there is a loss of power. The previous style factory GM plastic 85mm MAF (w/ screen) does not pose any loss of power below 500 rwhp Actual, and it may even not above that (to be fair, I haven't tested the factory MAF w/ screen above those power levels). This shows me that there's still sufficient flow through the factory screen, which is more dense than most of the aftermarket screens I've been seeing tested as of late.
With that being said, there is a good thread over on HPT that shows some before/after results with aftermarket screens on guys with larger MAF housings. I'll be testing a few different cars with these screens soon (unfortunately, I don't have any new Camaros lined up at this time, but hopefully that'll change). See here (read the whole thread for before/after results, and the various screens used):

One of the nice things the screens gave to these guys was even a drop in Hz, which can help on those close to pegging the MAF table limit (that won't be an issue on the the Gen4 vehicles with the 15k Hz limit, like the new Camaros).

Not to sound crude, but unfortunately you aren't able to see the bigger picture. A tune can't cause the airflow going through the MAF to straighten up. There is a bigger issue at hand here. What "feels" good isn't best.
