I wouldn't willy nilly unplug sensors related to the aftertreatment system because the software that controls your ECM is "looking" for specific engine operating parameters in order to run properly. Now, if you'd like to reprogram the ECM for a diet, shall we say, your best bet is to go north of the border where writing those kind of computer programs won't result in an appointment with the feds. And that's the last I'll say on that topic. 😉
