Default Stutter at low rpm WOT - 09-13-2017, 01:55 PM

Running MHD stage2+ 93 Oct, FBO with inlets. When hitting WOT at 2500rpm to about 3500rpn the car is stuttering and you can hear the boost pulsating like a fluttering noise.

It's an 09 n54 stock turbo. No check engine light. But I'm not sure if that's because of the MHD tune, only because it doesn't throw a light for the dpipes

I am not running a jb4. MHD flash only. My car would never run correctly with the jb4. I ended up ditching it and haven't had a cel since.
