It might possibly be a ruptured turbo hose, or one has slipped off check the elbow right near the turbo and connection at the throttle body. Go for a drive and see if you are getting positive pressure as the turbo spools up - sounds like you are loosing air massively and freaking out your ECU.
Symptoms you describe are identical to what happens when the turbo hose blows off the throttle body. I had similar symptoms with a torn elbow and when I had a hard to see tear in the hose at the throttle body. You just jacked all of those hoses around during your recent repair, so this is a possibility.
