Log looks quite decent, but you could run it richer already in midrange. 0.8-0.81 lambda instead of what you have now.
It does not hurt power. But not super important.
Also, your intercooler is quite done, you can see 50C IAT at end.
If you want to run this amount of boost, configure the overboost function and make it be active for max 10 seconds.
Set TVLDOBSO also a little higher than 1 second, maybe 2 seconds or so, so it does not get reset on gear shift.
And then TLDOBN has to be set based on when the EGT has "cooled down enough" that overboost should be possible again.
Most likely this value could be set quite high.
Different behaviour in different gears can also be accomplished with FKLDOBG, although as I said before, I don't think this is the solution in this case.
There is no point to start limiting it until the car has been WOT for 10 seconds or so.
For logging if you have a J2534 interface you can use my logger, it's free for ME7:

With that it should be stable.
