Tuners can turn off the egr... what the tune does is the same as unpluging the egr on the 6.0... the valve stays closed and you get more low end power and less boost up top the... the physical block off just improves air flow ...I've heard that an egr delete is cab off procedure but im not 100% sure on that just yet.
