I attached couple of logs with each map (still learning to read cobb logs, but I see a big difference in requested and actual load in one of the logs) Any opinions? Thanks for looking.
Yep, you've got a boost leak. The most common places to start looking for a leak is the FMIC and charge pipe connections. How long ago was the FMIC installed? Normally when is installedand then immediately after issues start occuring it's that part.

Boost mean abs is actually where the DME gets it's actual load, so when it's not hitting boost target you won't hit load targets. When you plot Boost mean abs, Boost and Load act in a graph they will mirror each other.

Other than that the log looks pretty dang good on both sport and aggressive.
