    2018 Cummins - MM3 Need Help!

    Hi, all hope I can get some insight into the two issues I’m having with my truck.

    1. When it’s in park idling I can hear the turbo spool up and down and whistle and hiss. I want it to be smooth and plain. Any ideas? Is that in the tune? Do I need a new tune?

    2. Sometimes I get a check engine light. It says multiple cylinder misfire, but it runs great. Only 20k miles on it. I erase the code and it shows back up randomly.

    Sounds like a tune issue, check with your tuner, perhaps they have an update.

    Can you suggest someone who does good work but is not too expensive to make me a new tune?

    Just about all of us are gonna suggest "redacted" and for good reason.

    Amazing tuner, but it depends on your definition of cheap.

    Thanks, how do I get my stock file to “redacted”? And are we talking a couple of hundred bucks?

    CCS tuning tried to get me for over a thousand for a new MM3 tune.

    As far as DRD prob more than a couple hundred.

    Follow the forum to his website.

    You'll need PW anyway and you can see for yourself exactly how much b4 ever calling him.

    @IGOTACUMMINS do I need to watch names such as here in this thread location or is forum entirely behind closed doors now?
