The reason I ask because I recently purchased Kooks Long tube headers and Borla S-Type exhaust for my 2012 5.7 Dodge Challenger R/T. I was told that this would require a tune?? I also was looking into getting the heads/cam kit from Arrington Motorsports. And then possibly a supercharger. Would love to get my car down to them. Just researching to see if there are any Mopar shops in my area.
