I'm headed off to class and then once I get back I'm gonna pull the coil packs and spark plugs and figure out which is bad. If it's a spark plug, I can have it fixed today. Question: Is it fine to mix and match spark plugs as long as they are the same heat range and gap? I have the FRPP replacement spark plugs in right now, but I'm not sure if a local store would have those. I know that they would carry something like Autolite though.

He told me he thought I was missing 75 hp. That would put me at 335 rwhp. If I got that, I would be pleased. I'm expecting 315 on the low end up to 335 or so top end.
An update for you guys: The car is fine today. Power is back, exhaust sounds like it should. I have no idea what happened. I did go ahead and pull the coil packs and look at them, and they look fine. I don't have a socket deep enough to get the plugs, so they will have to wait until next weekend. I'm going to try and re-schedule with Mike for next week.

I went to the dyno today. put down an amazing 258 rwhp. lolz. I have a spark plug or a coil pack that's gone bad. After class tomorrow I'm gonna figure out which it is and what cylinder it's one and get it replaced. I've never had one go bad before. I could tell a difference in the exhaust note, but I thought that maybe my midpipe had just come loose and I had a small exhaust leak. Oh well, at least it isn't an expensive fix.
edit: AFR was deathly lean too, around 14. Gonna do some datalogging tomorrow and get it fixed hopefully.
Anyway, it was a huge letdown for me because I've been crazy busy lately and this was the bright spot of my week. Either way, thanks a lot to Mike at Unique Tuning. He's a really nice guy and I enjoyed the experience, even if the results were inconclusive.

Based on your mods I would say you should be around 330HP (that would be my guess).

If you have a bad coil, then one or more plugs should look wet.
You should also feel a vibration under load. Mine was probably exaggerated because of the blower, but it was quite obvious from the vibration and exhaust note that something was wrong.
