Hello,
I asked my mechanic about this but he was not sure what’s wrong, so he will futher investigate next week. Unfortunately I can’t stop thinking about it so I will ask for your opinion.
My M240i runs perfect when it gets to temperature after a cold start. After driving for 20-30 minutes (especially in heavy traffic) I feel like the turbo spools up so slow and the engine does not rev up as quickly as it used to do. My car runs a stage 1 map, everything else is stock.
I am leaving the datalog and an video (also I hear a strange sound) of what I am experiencing.

Please, share your opinions.
Thanks!
