I want to run it at 30:1 for NOx reasons.

The mix across all four cylinders has been good. I'm still messing with individual fuel controls and feel I haven't dialed it in yet.
30:1 with shorter gearing or smaller tires will put you back in the zone where you're making optimal power to not overload the engine. There will be more wear on internal components due to engine speed, but meh.
