My Edge w/attitude showed an EGR code, but no code has shown on the truck's DIC. Anyone have an explanation? Only other mod is a straight through muffler. :confused:

DTCs don't show up in the DIC and they don't alway trigger a CEL either. Is it a P0401 that you saw? It is probably caused by the muffler. You may need a fingers stick or just keep clearing the code with the edge.

The finger stick has helped me on mine, but fingers claimed it does not help. Good design fingers. :) It is multi tasking.
