for dpf delete, can u just remove pressure tubes and sensors and replace pipe? it would not show pressure buildup and therefor would not go into regen?
wrong section, needs to be in the performance parts section for the 2007.5+ trucks. hopefully the mods will move this.
in answer to your question, no, you can't just do that. you have to either run sims, which fool the ECM into thinking that everything in order or you have to reprogram and turn it all off. if you don't do one of these, the truck will realize that something is unhooked and throw codes and put you in limp mode.
