2008 6.4l 105,000 mile

This is my first Diesel. I just noticed an issue that i can not figure out.

on acceleration there is a chugging noise, it will not get over 5psi of boost. once i get up to speed and cruise the noise goes away. I checked all the CVC boots and all is good. only modification i can tell on the truck is aftermarket intake and exhaust.

I have heard that it might be EGR issue- i dont know how to check or possible a turbo actuator issue, but i dont know if that will cause the chugging.

any experts on here that can help me diagnosis this issue. Please help ASAP, I have a trip in a month to SC to help grandparents move, and we need the truck!

UPDATE:

I took the ERG housing off and was unable to remove the actual EGR. I cleaned everything as best as i could, put it back together and took it for a test drive no changes.

I did notice that there is a modification that i didnt notice previously. so the list of mods are as follows...

1) Intake
2) Exhaust
3) ERG Cooler delete

Please help me figure this out!

UPDATE:

I took off the EBP and cleaned it and the down tube. The chugging noise is still there on acceleration!

The turbo actuator- I can move the lever with engine off, it returns back, with the engine on the lever will not move. This makes me think that the actuator is working right. however, i am still only getting 5 PSI of boost.
