I have a 2011 f-250 and took it to the delaership and they told me egr system is leaking fluid causing the CEL light to come on and making truck go into limp mode. I was told that it would be cheaper to just delete the EGR and i was wondering what all is entailed in doing this. what all do i need? what is best brand of EGR delete kit, what tuner, how much am i looking at in total cost? any help would be greatly appreciated.
