So since i had a 100% match on the ori with a complete mappack i had a quick look, which i really regret now.

This file is utter garbage in my opinion. No wonder you're experiencing overboost with this file. See the steep LDRXN increase down low. Pair this with the changes in IMX and LDRL and you have yourself some fine overboost DTC's. Not to mention all the things that havent been properly altered.

And also, what is going on with HBN? Is this a copy/paste error? I dont know, but it looks very strange. And with the pops change in KFZW youre surely going to experience some serious engine shaking during highway driving.

I have tried to attach some screenshots of my quick OLS check. Hopefully you can see what i mean.

From the logs, i also noted, that the car is running very rich. Probably off BTS. Both BTS and LAMFA havent been touched either.
