tuner help

  1. Performance Discussion/Modifications
    I have a 2014 charger RT, and I'm wanting to get a tuner for it. Does the pcm need to be unlocked before I can use a tuner? What's the best tuner? Any and all help would be greatly appreciated. Thanks

    I recently upgraded chargers and want to know if my tuner will work on my new car. And if not what is the best tune for the money on a 2015 RT 5.7 redline?
