I'm not familiar with BM3, but looking at the logs, they don't seem right to me. Your boost target is starting at 20.3 and then once meth kicks in, it's dropping to about 17.5. The change in target is expected in map 3, but the target starting so high seems wrong to me. That is why your WGDC is maxed at the start of the pulls. Looking at the CSV, it looks like your FUD value is set to 10. I'm not sure what that's for?

It also looks like you're letting off of the gas 1/2 way through the pull? Are you physically doing this? Or is the pedal floored the whole time? That is definitely screwing with your logs.

First couple logs had overboosting but then it learned down. Overall they look healthy to me. Anything concerning you?

thanks for the reply. the pedal is 100% until near redline, so not sure what would be causing this to show otherwise.

the car just doesn't feel like i'd imagine it should. 100% throttle, the car studders a bit. What's causing the miss to target early on? Overall, just looking for help tweaking settings based on what you guys are seeing, to iron out any issues. The help is appreciated.

Just to clarify, the pedal is showing 100% throughout, but your throttle value dips during the pull. You can also see the fuel trims acting up (fixed value of 25) during that time. I'm not sure what's causing that, or if it is even a problem, but IMO, it's something that doesn't seem right.

Throttle closes a bit because of over boosting at that moment. It's trying to regulate boost pressure around the target. A few more runs and it will learn itself down. The other logs he was over boosting a lot more.

It would definitely be much easier for you and more consistent. I don't know dont if you'd really gain anymore power though to be honest. Maybe a bit more because of the more aggressive flash.
