im new to the diesel world . I just bought a 2009 crewcab duramax . I have got to say that this is my favorite truck so far . Im wanting to do mods . My question is can I do a DPF delete without a tuner for now or is it like a ford and shut the motor down ? And where do I find a EGR block off plate ? Im doing EFI live but im not sure when . Any advice will help

 

You will need a tuner such as EFI Live

You will need to delete DPF, EGR, PCV reroute, and tuner at the same time.
