    I'd be very interested in knowing how you got 600 plush and 2050 torque? I have a red top supposedly 525 in my winch truck. 18 &4 engine flat doesn't perform with my b model cat. I'd appreciate any useful suggestions?

    What's your CPL? I can tell you if Cummins re-rated it to 525 it yas the low box program and is not impressive.

    I got my dealer to put a 550 h.p. 1900 ft-lb program in my stock N14.

    It is a Cummins program for off road haul trucks. It pulls good but it does make some black smoke when you shift.

    When dealer called Cummins because upload kept failing, Cummins told me they wouldn't do it because my driveline wasn't rated for it. I told them "I own, I drive it, it's paid for and if it blows up I'll part it out."
    So then they gave it to me, LOL.
