Looks like a MAF problem to me, AFR is on the lean side and with a boost leak it would be rich. Could be because of E85 adjustments, nothing unexpected. Also the difference between actual and req looks to be only <100mbar in the maf unhooked log. You have a known well working maf around? Boost leak test is always good, but I am not convinced that is the problem.
Maybe i have this backwards, but it looks like it is struggling to pull fuel here
0.82 lamba control is no joke.. as is 100mbar at only 600mbar of boost.
And if the problem is "MAF too high" it would ALSO be rich.
