Hey all, thanks for checking this out, now right to it then. My car is a 2012 335i xdrive (N55) with the major mods being BMS intake/charge pipe, JB4, and running catless downpipe and exhaust.

I could go into the history of how this started but I want to see if this jumps out as obvious to others.

The car has an odd pulsating power when just casually driving up a hill. going WOT it runs totally fine. I am also hearing turbo flutter (turbo surging) when I let off the throttle at times, I haven't been able replicate it 100% yet.

Looking at the logs I am thinking it is the Diverter Valve that is going out, but I could be wrong, and I hope I am, I hear that with the xdrive system, it is way harder to get to it. other things that I think it could be is a leak in the intake after the turbo, I still have the OEM plastic piping and IC. I know already I have a small leak in the vacuum side after the filter from doing a smoke test. What are your thoughts on this?

I've attached photos of a log from just driving down the highway using cruise control, and the saved fault codes I have been getting.
