My F-150 ecoboost runs super rich when first started when cold. So rich that it will puff the black/unburnt fuel from the exhaust. This will happen when just idling or first accelerating off when the engine is completely cold.

Once the engine is warm the exhaust looks fairly clean

Anyone else noticing this?

PS I am aware that all engines run richer when cold until warmed up. But I just want to see if all ecoboost engines are doing this.
