I removed the EGR valve, tube that goes to the DS ex manifold, DPFE, EGR solenoid near the back/center of the manifold, and corresponding vacuum lines. No tune yet to properly delete the EGR, no CEL because the light in the dash doesn't work. Truck runs great, good power and no pinging. Been averaging 20-21mpg mixed and hit 23mpg highway recently driving with a lead foot.
I deleted the EGR as part of the composite upper intake swap I did recently.
