Test / publish with 91 simply because that is what the bulk of the country (and most of the serviced world) has access too as their premium fuel. You would be about 20-30 horse down on 91 depending on conditions from advertised with the stage 4 setup. On the stage 1 tune with 91 the gain is minimal and really only evens out some power delivery--- seat of the pants feels different/better but actual power gains are negligible.
