Beau, I've blanked both sides of the EGR. It's broken on the throttle side.removing the EGR shouldn't change the turbo sound or engine noise for that matter.
Could you take a pic of this line that you're blocking off that changes the engine noise, I'm intrigued...
The same line in the picture above is the one that creates the sound. It's the line that was supposed to go to the small actuator. I had the hoses connected incorrectly.
Some how that "black cap" was removed from my solenoid. Under that cap is a vac line port. That was running straight down to the vacuum pump.(wrong setup)
The hose in the picture of how mine was shows the lower vac line on the solenoid loose with the top one going to the small actuator.
Whenever that second is blocked it starts to sound like a perkins.....
I'll post some pics. But you can check also that picture I have uploaded. I labeled which line was loose. When that loose line is blocked....... And also the "black cap" that is missing on my solenoid.
