My understanding from the EFI 101 class is that when not under load, it's OK to lean out as far as your car will go. They said to find that point you lean it out until the car just doesn't behave correctly(bucking etc) and add fuel until it's all smooth. **This is NOT under load and is in the cruising area of the map.** This is a very simplistic post about how to do it, but you get the idea.

The basic thought is this.. When not under load, leaning it out does not create extra heat. The less fuel, the less burn, the less heat is the way EFI 101 put it. I can pull out my notes from the class to quote exactly if needed, as I was very interested in this exact topic, and we went over it extensively..
