you're not going to see a huge difference over the programmer you already have. the Mopar Performance PCM isn't going to be any different that your stock PCM with a power programmer on it.
there's only so much you can get out of the engine as it is. to build more horsepower, you are going to have to start from the inside out. pistons, crank, rods, camshaft, heads, intake, ect., ect.,,,,
buy a 408 CI Magnum crate engine for it.
