Leaking Injector? Logs Attatched

[BarelyMovingWreck]

Hi all, pretty new to this platform. I've had my 09 135i N54 for a few weeks now and I was doing coils and plugs and MHD tune yesterday when I noticed my #6 plug (as well as 3) was pretty fouled up. The car has rough started about twice in the three weeks and I had a friend look and he noted that there is a small puff of black soot that comes out of the exhaust when it rough starts warm and a little during cold starts (too small for me to see out of the rearview). Car pulls hard and meets 13psi target boost according to MHD app.

Attached are a picture of #6 plug compared to another plug and a datalog for a cold start (ran a little rough but didn't soot this time), and idling when warm. Can someone point me in the right direction before I spend $1400 on injectors? Mine are all index 9 btw. Thanks.

Cylinder 6 and 3 are fouled but also seem to have some oil on them, added other plug for reference.

Check your gaskets. Vcg especially. I was leaking oil in 3 and water in 6. The 3 was vcg. Wasn't ripped, just bunched up. I replaced it anyway. Cyl 6 was from my cowl being removed and bms filters on and water getting in it. I cut my current cowl to allow water to channel off and still keep the bms filters. If you dont have bms filters its probably oil. My watered plug well had a tan fuzz in it

Looks like Oil on the plug? Smell it.

If it's oil it's probably your valve cover gasket, common failure point. They leak and or crack.
