My 30FF code was from worn out vacuum lines, $5 fix. Mine were leaking under the engine cover though on the top front of the engine. When it happened to me, I had only a Dinan S2 tune on it and the increased boost just killed the vacuum lines. Just replace them and was good as new. So a smoke test is what I would do.
