In any case, your sensors sound ok, and it sounds like this is a common problem. Maybe include a PCV and vac line and/or catch can? If OEM PCV isn't up to it, I know there are aftermarket PCV's for boosted applications.

We would have to tap the intake piping to route the PCV back into the system. Currently it's vented with no nipple to attach to on the intake piping leading up to the throttle body.

I'm very interested to see what happens when Mitch gets a catch can and is able to drive around without the PCV system completely.

On a similar note I order my O2 bung plugs and will get my tuner to update my map to disable the code this week. See how much that helps the idle issue. Any true tuning updates will have to wait until I get the V1.5 piping.
