Rough idle/slow boost build up

I have an 06 f250 6.0 4 inch exhaust, sct livewire currently set on the street tune. My truck is occasionally slow to build up boost on moderate acceleration, and when the truck is hot it will build up boost fine but ill have a rough idle when at a stop light and it'll kinda spit and sputter upon acceleration but will be fine once I get up to speed and let off the throttle. Has anyone had any similar issues?

Ive noticed mine also does this but more when towing. I am running same exhaust but otherwise stock.. Last trip pulling a car trailer with a side x side we noticed diesel on the trailer. I am suspecting i have a leaking injector. Not sure that my scan gauge II would catch this sort of thing.

when the idle is bad like that are you noticing the exhaust smelling really heavy? mine does

I had a friend come by with a scanner last night and we found #3 injector not behaving... have you looked into your issue yet with a scanner?
