I run mine at 14.7 with 4% ego correction so it oscillates up and down a bit.


**I'm not an engineer and they can feel free to correct me**

Detonation should not be a concern at cruising loads. The cylinder pressure is relatively low and unless you get insane heat build up should not be a factor. I've heard of guys leaning out the mixture as much as possible to improve fuel economy, though I don't subscribe to that theory. I've found that as I get leaner (above 16:1) on deceleration I get lots of popping from the exhaust. This is because there is not enough fuel to get good flame propagation in the cylinder and you end up pumping fuel into the exhaust system where it ignites and pops. Because of this I feel that if the fuel isn't burning in the cylinder, it must not be as efficient.
