    2012 Chrysler 300s cam tune help

    I was brought a 2012 300s to tune after a MDS delete and a small cam was installed. I'm a GM tuner but thought this would be a pretty simple tune. it has not been nothing is the same here these dodges seem to like 0 or negative timing numbers witch makes no since to me. I have been able to get the car to idle pretty stable and run down the road pretty well the problem is it stalls when coming to a stop once in a while and almost every time the car is put into park. when that happens timing goes negative and it stalls. Can any dodge guys provide some incite on what is going on here and how to fix it?

    find below the current tune file and the log of what its doing.

    What cam is in it?
    If in doubt, multiply everything by 1.1.

    that gave a little insight but that car has a blower on it so alot of the changes he made were for the boost as well as the cam.

    I'm running this same camshaft with shorty headers, muffler and MDS delete in a 2011 Ram. I've had the same issue with it dying. I'm an school screwdriver and timing light guy so I'm working through this slowly. So far I've bumped all idle set-points up and disabled the DFCO. That helped a lot. Still working through it all. Are you seeing yours run really rich with this Camshaft?

    Really is a shame people don't come back here and explain what fixed the problem. It becomes TOP SECRET. Little disrespectful for the people that try and help them.
