    Ram 2018 VVT tuning

    Hi can anybody explain me how to tune the VVT table

    dvertised Intake Duration: 274
    Advertised Exhaust Duration: 287

    I dont know what number to put in the WOT angle base table.

    I also do have a problem with the idle when i turn the accessory on the idle surge without it the idle run perferly fine.
    The truck is verry lazzy in low rpm no low end torque, i cant pint point the issue in the tune.

    Thank you.

    Do you have the standard read. What u have done to the WOT cam table looks good. Id copy the same stuff to the PT table too. No need to run the factory fake EGR in a build like this. Full advannce at PT will bring some life back. Id try switch the NN back on and tune the Inj PW for simplicity and see if u can dial it in

    Is it the Comp 274 cam? Idle is the toughest part, I'm working through mine now. A/C on seems to affect it a lot. I've been in the idle airflow tables, trial and error. Compare with this tune in that section, not mine, but what I used as a starting point.
    Good read here.
