Yes I have. It is one of two things for certain. Either the there is an exhaust leak pre-O2 sensor or the O2 sensor is toast. Easy why to know is replace the gaskets, at which point I will know. Got the tune and boost sorted out though. I am hitting 21 psi reliably now. So thats all good.
Schweet, get it up and running so I can beat you down.
