Airlimit source and max sources can all come off, as well as baro, inferred octane, charge air temp, and others. When diagnosing a problem that happens so fast, you need dense data. I would add "commanded" lambda to the list, though, also on a high data rate.
Another note is that you're hitting the cylinder pressure spark limit. That's an easy one to get around if you so choose.
