In an effort to eliminate this as the cause, I have been sneaking up on more advance one degree at a time, listening intently for any "pinging". The timing was at 28 degrees total when this happened. That does not seem excessive, but could that have been it?

Seems too coincidental for it not to be the cause... what's the total timing on factory twin plug engines like a 964 or a 3.0RSR?
So one opportunity that might present itself is to bore out those MFI throttles and stacks a bit?
