i've done the spark plug thing to no avail... nothing is working. I know my egr port should be cleaned and dpfe sensor replaced also but I haven't gotten to it. and I know about the legality of it all. In all reality I would probably leave the front two cats on for convenience.
basically, I just need to know if it can be tuned to make the truck ignore the fact that my emissions system is out of wack. like, send it a false read
