    What do you mean RPM is high?

    If that's power to the ground, I would say its fine. We dyno'd a new 500 hp Series 60 many years ago and saw 411 to the ground.

    84% of rated power to the ground is good. Most common reason to do a dyno is to measure blowby and hp to the ground. Just measuring hp seems a waste.

    Where is the blowby, the most important number. But because it is above 75% of rated power, it looks good.

    this is what i got reply from CSM KENWORTH...they are not allowing me to take truck to another shop...

    (There is no way to measure blow by on the newer dynos. We have not measured blow by for years.)

    I did this on my 2014 ISX
    ETA: No, this isn’t me. I went to Lowes and bought the stuff to do it just like the video.
