    Actually I have used the newest low nox files,and like 550 said they are STRONG and make good fuel mileage.

    Any cat service dealer can hook up Cat et and give you that download. This will tell all your parameters. You may have to pay 1/2 hour or something, but then you would know.
     
    WallyGator Thanks this.

    will the cat dealer turn it up to 410 if its set lower? or do thay have to have some kind of password? should i bring my rebuild sheet with the part# on it so i can prove the 410 parts?

    I don't know what they would charge you for that if it would be worth only going to 410.That engine was set at 355 new.

    Broncrider and kaliga1961; What are you guys with the 435hp 3406E's getting for boost pressure? I also have a 5EK 3406E with 435hp and I can get to 34-38 psi on a good pull if its cold outside. I am in the middle of rebuilding my motor (435hp) and was told by DDS in another post that I need pistons, cam, turbo/injectors and ecm uprate for 550hp/1850torque.
