Chugging

so i noticed when doing about 40mph if i get on the throttle i have a bad vibration and "chugging" feeling. Boost gauge dont fluctuate it stays steady. To me it feels like a dead cylinder. Im thinking injector not working but i was also told it could be the EGR and/or EGR valve. Im hoping EGR since it will be gone soon anyhow. Theres no lights on in the dash. Any ideas?

you can feel it lose some power and the RPM gauge will go up and down but barely. Id say 150-200RPM. Im wondering maybe injector is dirty? i found some oil in my inner cooler elbow but not much. I had an oil leak around my oil cooler for awhile so im thinking some oil got in and made its way through the intake. That problem is gone now.

The oil in the intercooler is normal. The crankcase vent (CCV) is routed into the turbo inlet and the oil goes through to the intercooler and into the intake.

You can do a CCV reroute or dump to minimize (or eliminate) the oil. It will help save the oil from soaking the boots and causing them to fail eventually.

Could be an injector. Do you have a way to do a buzz test and contribution test? I had injector 6 lay down on me no codes, no smoke just bucking which was worse while running a tune. Stock tune didn't happen as bad. Tried HSS and switched to Rottella T6 to see it would help and didn't do much good. Finally did a contribution test and you could see it dropping out. Replaced injector and truck was happy again.
