I've had the cats removed on my truck which causes 2 codes to appear. The tuner went in and programmed just those specific codes out so it has no effect on anything else. It's probably a bit more complex here, but I would hope it's the same general principle where they tune out only specific codes leaving all the others.

I'd still like to run the potential scenario past them and maybe get some more insight on their process. I may be blind here, but I can't seem to find any e-mail address or contact us link on their webpage. Does anybody have their e-mail address?

I’ve chatted back and forth with the owner of DUDMD tuning a lot, and it basically is the same principle. Monitoring and codes for just the emissions parts that are removed are blocked. Then you also have some tweaks to the tune maps to get more power if desired (do it!).

You can find DUDMD Tuning on Facebook. Message them. Dmitriy will gladly answer your questions and put your fears to rest. He’s great to work with.
