Have you checked your MAF readings?
In the log you posted they make absolutely no sense.
At 3240rpm it reads 127.31g/s and at 3360rpm 198.72g/s.
It is just not possible.
Also you are making far too much torque at too low rpms.
1.76 bar of boost is a rod killer when the rpms are so low (3300rpm).
The engine is running way too rich from 3500rpm and up.
You could easily make it leaner by 0.1 as the optimal is between 0.85 - 0.8.
In few spots you are already getting torque intervention as the lambda exceeds the protection threshold (actual is 0.04 greater than requested).
I´m no guru but I would personally start making a new software from scratch.
The current one is not safe to run IMO.
I find my MAF reading weird as well, i've originalized the LAMFA map.
I've italian set KFLDHBN to 2.5bars, it shouldnt hit the rod breaking boost this time round.
Gonna log it again and see if i hit anything near to the AFR specified in KFLBTS.
Thanks for the hint.
