You're still way ahead of me.

I thought I had auto-tuned all tables. Yet found it going lean when 
added throttle to climb around 4,200+ RPM. Disconcerting. Could be 
change in AOA influences intake. Need to fly and tune more. Only 33 
hours in the air so far. And yet now have to do annual condition 
inspection :(
About 3 shots of prime in 80F + temps. More in colder temps.
