I'm not any further along than you are, but I'm finding that most reports of damaged engines relate to inadequate octane, poor fuel quality, using the wrong "tune" software, using generic "tune" software that is not a close enough match for a specific combination, and/or a defective/failed fuel pressure sensor on the low-pressure side of the fuel supply system under the hood.

Most of those failures look preventable to me.

That fuel pressure sensor will apparently cause the engine to lean out under boost. It can be monitored in real time, using an aftermarket hand-held "tuner". And Ford has an updated replacement part available.
