AFR - What is Optimal ?

I've searched using 'optimal AFR', 'optimum AFR', best AFR', and many other permutations - I haven't found anything close to definitive.

So, for an EFI controlled non-turbo 911, for perhaps 3 ranges:
idle, acceleration (strong), and cruise - what AFR's should be targeted?

If someone has links or referrals to either pelican threads that deal with optimal AFR's or technical discussions relevant to 911's, whether opinion or theory, I would appreciate it.

The goal criteria here is max horsepower within reasonable engine potentials - not fuel economy nor testing breaking limits.

thanks,
Jim
