Here is the picture I have been waiting for..
Run 1 15psi e20
Run 2 14psi e20(loaded tune on dyno)
Run 3 stock with e20 fuel map(loaded tune on dyno)
This shows that higher boost does not always pay off

I dont see the green line at all?
I think the run # on the min/max/avg is not the same as the colors below? Looks like 14 and 15 psi are pretty identical, +1 peak HP on 15psi (with adaptive) vs. + 5 peak tq on 14psi without adaptive. Where temperature, etc. the same at the start of these runs? if the car was heatsoaked/hotter on that 15psi pull then it would have been pulling spark.
I could see there being difference from 14-15 psi depending on conditions and efficiency, but based on the max numbers it looks pretty negligible (if conditions were the same). Lack of adaptive means the 14psi may be slightly better if it was fully adapted as well. IMO for your case, I would run that 14psi tune.
