So my buddy has a 2012 challenger r/t and I put a cat back flow master exhaust on it a couple of weeks ago. Well today I asked him if he still likes it and when is he going to put a cai on it. He told me there was no use cause no body has a tune for it and caint tune it!! Something about that nobody has cracked the programming and Chrysler want release it. That is the stupidest thing I have ever here of. Chrysler needs to get there stuff together and release the programming software Some guys are putting 2010 ecu on them and re flashing them to run on the 2012. If I'm not mistaking but doesn't Bama tunes and ford work with each other.
