Let me know if I'm in the wrong spot please.

So been tuning my car with MHD for two days. I am experiencing a odd noise, like a low whine/ whistle from front driver's side. I want to post logs but want to know best practices and can't find that info. I did a Stage 1 91 oct and moved to stage 2 91. That is when I noticed the noise, I hear it on stage 1 as well now but not when flashed back to stock. It only happens while accelerating up to around 3k rpm then goes away. Thinking maybe air box not sealing around the filter or charge pipe? No drop in performance.

I have recorded logs at every stage but they are 10 minute drives. Should I record a shorter time and then point out at what time I'm hearing the noise? One log attached but not sure if I am doing this right.

2016 M235i 6MT, upgraded charge pipe, boost pipe, intercooler, turbo inlet, stock plugs and coils

Welcome to the party! As I am only a Brigadier General I may be of limited help. I assume my associates will be able to help.

Take a log going WOT from 3rd to 4th. Make sure timing corrections and fuel psi is recorded.

Welcome! What Torgus said about logsšŸ‘

Not sure about the wine/whistle sound, any chance you can capture on a video?

I think I did it right, rush hour traffic so difficult to do. You should see where speed increases at 2500 rpm
