Not sure what's wrong. Doesn't run...

A few weeks ago I drove my 2006 AT Coupe and everything was fine. I went to start it up recently and it idles horribly and almost immediately dies. I'm getting no codes.
It runs in limp mode with MAF sensor disconnected.
I changed the PCV Valve and MAF sensor but neither fixed the issue.
When MAF is disconnected it throws codes but none when it's connected.

FYI, I have a Vortech supercharger.

I'm stumped. I was thinking cam shaft and crankshaft sensors but everyone says that those should throw DTC codes if they are bad.

Any thoughts?
