anyone ?

Well as you might know the afr helps to cool down the combustion chamber, so running lean with to much advance and boost can be dangerous.
I look for small little puffs when doing dyno pulls.
Another good way to find the sweet spot is to run some 100 octane, retard the timing a bit and walk it up until the power starts to just drop off.
Once it just starts to drop, back off a few and call it a day.
I go with 2-3 degree increments.
This is not for the butt dyno.
50/50 water methanol injection will allow you to run max boost and timing on pump gas, works great.
I time G60's per the factory specs, unless I'm squeezing juice or running mega boost on pump gas.
Then you can back it off a few.
I'm certainly no guru engine tuner, just my personal experience so I thought I'd share.
