Default Jb4 c43 running rough / throwing engine lights /low boost - 11-01-2020, 01:03 PM

I have a 2018 c43 with jb4 only. Run 4-5 gallons of e85 with a tank of 93. For the past week I've been seeing engine lights daily for 2177 and 2179 codes. Also the car is running sluggish on any map. It will often hesitate/ jerk after startup and driving until everything is warmed up (logs attached). One morning it nearly stalled out and rpms jumped around a ton. Logs show boost levels not where they were on previous runs on map 2 and 3. What could be causing this?
