I was planning on getting a ZZP pcm, do they set the codes to no reporting or do they completely remove them? I would like to have the computer know it has a bad CAT but just not show up in emissions check so I pass that way it wont keep running it since it will think its bad. Also can someone hook me up with Overkillwill's contact info cause I'd rather pay him to get the actual diagnostic test completely removed so it will never do that test again.
