    Yupp imagine the ones that have purchased there first ever ram Cummins and didn't know about the CP4

    They will probably never come back to ram (forever hating) once the pump starts killing itself.

    Here look at it this way, there is a reason Ram and Cummins went back to a CP3 after only two years.

    A good friend of mine just had a Catastrophic CP4 failure on a 2015 Duramax 3500 Denali about four weeks ago.

    The total bill will be $26,000 dealer quoted.

    The motor went too much damage from metal; this was a nice truck about 70k miles.

    Oh, GM says they will pay a whopping $2700 towards the total bill.

    What a joke!

    Wow, now I am worried about my 2020.

    It is all stock, so I know the warranty will cover this, but I would like to avoid it if possible.

    The S&S no-tune conversion is $2,700 on their site, not cheap insurance.

    If I do the swap, should I go with the SS or the no tune if I plan to tune the truck later?
