Pete,
Check all of the electrical connections, especially the connector at the air mass meter. If that connection is weak (or off completely) you'll be in "Limp home mode" and it seems a little like what you are describing. Couple that with one vacuum leak (or more) and you've got a car that will barely run at all. A single large vacuum leak could easily cause the problem you describe. Check the large hose to the boost bypass valve thoroughly and check all of the vacuum connectors on the intake manifold. A bad air mass meter will usually cause idle undulation when cold but will work better once the engine is at normal operating temperature. Keep us posted.
