It's having to add excess fuel to hit afr target. Is it the same cylinder misfiring every time?

I believe it’s cylinders 3 & 4. I initially threw codes for 3 & 4 and then hide cylinder but it didn’t specify which one.

Looking a bit oily too for just being put in.

I agree, the oil was there when I took out the olds though I didn’t clean because it was far down so I don’t know how old that is. I peaked in 3 and 4 with a borescope just now and nothing is hanging around in there. In other words they look fine. Continuing onto 1 & 2

Can we see? You want to look out at the edges that's where you usually see issues. Throw em up on flickr like this:
Why would you think your tune is garbage? Who did it? How long have you been on the tune and that hybrid? Need more details. Assuming you haven;t touched the boost sensors you could flash to stock and see how it runs.

Not done my hybrid yet, I was doing maintenance coils.
I’m a stock turbo tuned on e30 by sneeky. Basic bolts ons, downpipe, intercooler. I can’t seem to get Flickr to work but I see a fair amount of what looks to be carbon buildup. No debris but the cylinder faces are a grey black color. Closer to black and the edges are not as defined as the video you sent. But they are visible.

Cobb OTS or stock will tell you all you need to know about the tune.

The same continues to #1 & 2. No metal just carbon buildup. Or what seems to be. I will return shortly after finishing up some work thank you so much for your help

Are you blending your e30 at the pumps or do you have an ethanol gauge? I wonder if your e30 is really e45 and it's running hot and maybe lean.

I am blending at pumps, I have a sensor and gauge and I test gas before I put it it. Always fall between 29 and 31.5. Once dipping down to 27 but that was a few thousand miles ago.
