I'm curious if the screwy voltages I'm seeing on my rear bank could be caused by a leaking EGR valve. You'd think if an egr valve was leaking, boost would be pouring into the exhaust, up until the point the back pressure from the exhaust equalized with boost pressure (6000+ rpm @ WOT). This would explain why I see a lean rear bank that seems to be proportionate to the amount of boost. I disconnected my EGR to see if this would fix the problem and this seems to have made the problem worse.

I'm going to try an EGR blockoff to see if this fixes the problem.
