Let's pretend that with cold air intakes, and/or performance exhaust systems, that the air/fuel ratio leans out - perhaps even leaner than ideal. How would I trick the car into running richer?

If you REALLY get the 6.1L flowing, it will run lean. :wink1:

Is leaner than 13.5:1 too lean? I'm thinking 12:1 could produce some power gains. Now that all that extra air is flowing, I'm curious about getting some gas flowing to match.
