Hi All,
I am so glad to read Rusty's honest appraisal of how it really works in this experimental stuff.  I'm thinking of naming my plane "Do & Re-do". 
 
Ten days ago in Pensacola, duh?, I set about to re-evaluate my mixture map.  (hint to Perry)(Thanks to Ed).  I found that the average setting, from 13" to 30" was 5-6 bars/10 on the meter.  I reset in Mode 1 to 7-8 bars.  Went flying and power was good. However, takeoff roll rpm was still low at 4500.  As we accelerated to 5400 in level flight, the mixture meter showed only 4-5 bars.  I adjusted to 7 and kept the mixture there for local flights at from 3-5000 with nothing but smoothness.
Questions: 
1.Why would the WOT mixture decline in flight vs. static WOT? 
2. Should I go for more TO power with slightly less pitch until it will generate 6000 +- with WOT in level flight?
 
Regards,
Tommy the lurker
ps WOT Temps never got above 197* with OAT at 60-65*, even at 80kt climb
