BMW 335i n55 2011 stalling on cold start, having to rev high rpm to fully start

Hi, does anyone know why my 335i is stalling every time I start it? I’d have to rev it high rpm to actually start it. I changed the chargepipe and pvc pipe, so not sure. Ignition coils and spark plugs also done to it as well with downpipe and mhd tune. Got someone to diagnose it, but they can’t seem to find any major codes.

Hi, yea I found a fix to it, I flashed the mhd tune back to stock, with mhd remain installed, maybe I flashed the tune wrong?
