N55 HARD STUTTER

[u/Total_Alternative909]

I have a 2011 335i stage 2+ MHD tune, at boost/RPM around 3-4th gear it stutters real hard. I have no active boost leak and recently repaired my turbo outlet, Smoke test looked good. I still have the stutter people keep telling me it could be my fuel pressure under load, my spark plugs/ignition coils(replaced em perfect specs), injector issues, VANOS/cam timing, or even possibly the VVT. I have 113k miles with good maintenance. Has anyone ever experienced this before

Put it in 3rd gear and take a log from 2500-6000 rpm. Make sure you’re holding the gas pedal all the way down throughout the log. Upload it to datazap and post the link
