I am a complete noobie with these newer cars,so please bear with me. I have 2013 Mustang GT with a JLT CAI and a pair of Roush axlebacks installed. I just downloaded the updates onto my SCT X4 tuner. I need to install a tune onto my car. I only have the tunes provided by SCT. Which tune should I put in it? I want to do some custom tunes eventually after a few other mods are on the car. Any help would be appreciated. Thanks. Mark
