I drive a 2020 F97 X3M and have recently transitioned from using the MHD OTS Stage 2 to utilizing two distinct maps provided by Odintuned. The performance logs for both the petrol and E30 maps appeared to be very good. However, I encountered an issue characterized by an unusual noise resembling a misfire. This noise was only perceptible at high RPMs, specifically before shifting gears, and occurred exclusively when the E30 map was in use.

In an attempt to rectify this, we replaced all spark plugs, adjusting the gap to 0.022, and also replaced all ignition coils. Despite these changes, the noise persisted.

Recently, while driving home, I experienced a significant loss of boost after accelerating and changing gears. I initiated a log immediately after coming to a stop. Subsequent attempts to accelerate resulted in the same issue: a complete lack of boost. Currently, there are no error codes present in the DME.

I have included a link to a video capturing the sound issue: https://www.youtube.com/shorts/X9cj7w9ZObQ.

Could you please review the log and suggest any potential causes for these problems?
