So the efficiency codes talking about being too lean and lambda probes, ignore them? Also a couple side questions: 1-does the “current mods” section change the tune at all based on whats in there, or what’s the section for? 2-what would be the recommended spark gap if just ctless dp’s and tune? Possibly e30? And would double platinum plugs be ok? Thanks
