2009+ 5.7 Hemi Eagle

With a wideband O2 the MS is pretty much plug'n'play and self learning, but the guys at EFI Source say you'd still have to do some custom work on the VVT end. That said, they aren't out to market yet for VVT. Holley is working on it as well, but not currently there.

So, in a nutshell, your best bet at this stage in the game is Modern Muscle or Hotwire Auto. OE computer, modified harness, and away you go. Add a fuel system and away you go...
