We use a block puck in front of the egr cooler so that is for some reason that line is bad we got it covered. You should check the turbo vnt control its easy if you have insite to calibrate it back.

If you make it in to Georgia come see us and we can check it out for you.

I thought that but I've pressure tested the CAC from the first boots forward. I have the Venturi blocked but not the Egr cooler, I'll take care of that. I do have insite so I'll also inspect the actuator and re calibrate it as well.
