    Cammed 5.7 challenger idle tuning help

    The car is a 2014 Challenger rt 5.7, it has an intake, srt8 intake manifold, compcams 218/226 cam, mds deleted and srt8 exhaust manifolds.

    The car just dies ramdomly, sometimes when going from D/R to P, sometimes when braking, sometimes it will just die when left alone to idle.

    Here is the current tune and a datalog

    tune3 ve.hpt

    as you can see in this log we drove around for a while and it was ok, then let it idle and at the end of the log he died alone
