    2017 Silverado throttle limited rpm at 6000

    We are trying to raise the RPM limiter on a clients supercharged 6.2 2017 Silverado.
    I have tried raising all the limiters to well above the limit we are looking for (6200) but still the throttle closes at 6000.

    I think it may be a coefficient setting but not sure.


    Thanks in advance.

    Ran into this before. The cold engine start up modifier needs to be raised up. This table is set to 6000 in your file. It is showing rpm limit as predicted torque source and immediate. The table description threw me for a loop.

    Interesting, got another truck I've had this issue on, I'll have to check that.

    It was fighting me for months and I finally tried adjusting that table and it worked great. Seems the time of 80s really means 80s and above. All I know is it corrected my issue.
