    426 vvt issues

    Morning yall,

    When I start my 2012 challenger srt8 in the morning I get a P0013 code for the oil control valve circuit is open. Once the vehicle is warmed up, the code does not return. The control valve does work, one of the logs I was doing shown the cam moving between 134.3 to 116 degrees. I have a phaser limiter installed and the cam is a comp cams HRT stage 2 supercharger cam. No blower yet seeing that the prices are skyrocketing lol. I'm just looking for some pointers as to how to tune the VVT portion, and here is the tune file that I'm currently using. Still tuning fuel delivery so that it's not running lean.

    Made some changes, started the car when the coolant temp was around 140.

    I think that you are retarding the cam way to much in the second tune. The first tune looks so so. I would not start retarding the cam until 4000 rpms or so at WOT.
