Alas, I don't think this will be settled without experimentation.
Broadly speaking, every HHO study I've found hasn't actually stood up to rigorous scientific scrutiny. They're generally snake oil.

There are some small benefits, such as hydrogen burning faster than gasoline and allowing slightly less advanced ignition timing, and the extra knock resistance, but from a total system energy perspective they produce 1/5 the energy they consume.
