Oil coming out of bypass valve?

YES!
You also need to clean out your intake manifold and anywhere else there is oil in the intake system.
There are articles on site about Superchargers creating large amounts of crank case pressure. Catch can will help, but you may need additional venting from what I have read.

Somewhere I found a listing of all the GM codes, including many not in my DashHawk info. Not sure where it is any longer though. You might do a Google search for GM diagnostic codes, and perhaps even for the specific code. Likely is related, but that's only speculation.
You can also start a thread with a question on this specific code. Am sure someone will respond with an answer.
Good luck cleaning out the intake. Dawn liquid detergent works good. I would put it in a soapy bathtub and slosh it around till the oil's removed.
Once clean to a paper towel or rag, you can blow it out with air from a compressor or a leaf blower. You will also want to make sure the ports in the heads are also wiped down, so oil won't carbon up the intake valves, affecting A/F mixture and making the Vette run crappy later.

P2227:
Barometric Pressure Circuit Range/Performance
This is caused by a mismatch in sensor readings between the Baro and MAP at cold start. A distinct possibility, since you have oil coming from the BOV, would be oil on the MAF.

If it is a dry sump car have you ever had the oil changed? Never put the documented 10.3 quarts in it. I only put 9 to 9.5 in mine. Anything more and it ends up in my breather / catch can and usually a mess.

Is this an issue that can occur with any of the three centrifugal supercharger kits, or is one design more prone than the other? From what I have read, these are the major reasons why this occurs:
1) Engine oil overfilled
2) Too much timing in the tune
3) The pistons are "hurt"

I had not attempted to fix it in the tune until several efforts over the last few weeks (unsuccessful) so i still think its a good experiment if he is game.
It does make sense that since we are commanding horsepower and not merely throttle angle that you could be commanding hp you very well don't want, and abruptly but at a certain point the grap turns up and you don't have much choice to 'smooth' Ill update that post!

correct on the first two, but on the third its actually not hurt pistons but rather the cylinder bores in the block are not as precise as they should be causing an "out of round" condition. This condition causes excess blowby which results in the spewing oil..

I have heard of the issue that you describe as well sir, but there have been reports of actual damaged pistons and rings as well; some due to detonation, and others simply to not handling the power demands as well. Please reference a few threads down by Vengeance Racing regarding their aftermarket piston kit.
