2008 ISX major turbo squealing

[Mr Hagg]

That sound is either leaking charge air boots or leak in you egr system. 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.
