wait. a dealer did a turbo R+R on this car and never shook it down?

that's some ****ed up **** right there.

you're on the right track with your thinking. the test you performed basically eliminated the ecu map and the solenoid and the wiring harness and the boost control system plumbing (hoses, restrictor pill etc) as the issue.

so what's left are the massive leaks or the wastegate not seating/sealing. certainly a missing bpv gasket is a pretty big leak, but i don't know if it's THAT big. a bad bpv itself could also cause this kind of issue (and is hard to troubleshoot because it doesn't cause a change in afr/cel).
