Newer Challenger/Charger forums

I like ChallengerTalk, but it certainly isn’t the same as FABO. Just not the need for the level of tech knowledge needed since most of the performance is already there. But there is a thread where a guy built a Hellcat swap starting with a 2010 Challenger V6 car, or something similar. And if you want to hack the BCM there is some good info.

Might try lxforums.com, they used to have some pretty savvy people and some cutting edge stuff.
