Hello everyone, Phil here, just traded my 2010 Challenger SRT8 in for a new 2015 Challenger SRT Hellcat. Love the extra hp and the feel of the Cat. Looking forward to doing a few mods to it. CAI, I have a Diablo Trinity Tuner, just need the extra brain box to swap out, muffler delete, and other things as time goes. Looking forward to all the information and help this forum will provide.
