I am running out of ideas. Car is a 2009 challenger 5.7 car standard with a 426 stroker and a comp 270 vvt cam. If I disconnect the battery the car runs great for 100 or so miles and then the idle goes to hell. When rolling the car will rev to 5000 rpm's or so on its own. When I stop it calms down. I can disconnect the battery and drive it and it runs great so I don't think that it is a vacuum leak. Any ideas? I've also increased the airflow values for the TB in the low range. That lowered the idle right after I flashed it but still the free revving came back.
