  16. Hello kriechbaum im jd and i wonder if you will make this sound for the pete 389 v4 modified truck? i hope so thanks. greetings from holland .

  17. kriechbaum

    Hello, it works for the modified truck. I did try it yesterday. I think, you should buy an another engine in the shop, and be sure my sound mod is loaded after the truck in the mod’s list.

    See you.

    1. Yes it works with the 550 hp engine thanks greetings

  18. Always the best, Maestro!

    1. Really nice sound, love the jake brake. Any chance of getting a Detroit 60 series sound for his truck? Or where you can change engines from cummins, detrioit, and catipillar?

      1. Hi Jk
        The 3.2 version of the 389 has 3 different Engine: DD series60, CAT C-15 and Cummins ISX, the sounds were an older version of Kriechbaum mod but unfortunately you cannot modify the turbo whistle volume that IMHO was a little to high in that mod.

  19. kriechbaum

    Currently this truck does not have multiples engines sounds. Later i’ll make a pack.

    1. You said earlier you use the 2.0 version of the truck, will your engines show up for the 4.0 version or only 2.0?

      1. kriechbaum

        this sound mod also works for the modified 4.0 version.

    Excellent mod.Thank you kriechbaum.

  21. thanxs kriechbaum my friend, you make sound for pete 379….i appreciate for your concern,my friend once again can you help me to setting the truck pete 379 the body chassis became lower,i think it’s too high. thank you.

    Krech, this one sounds more like a CAT than it does a Cummins. I’ve ridden in a couple Petes and I can tell you that this is what they sound like with a CAT under the hood, the Cummins (usually an N14 or ISX) sounds different.

    They hate So much Loud Turbo, so my Update mod has less Turbo Volume.
