I'm running a Hemi6 controller on a 2005 5.7 Hemi out of a Ram truck. I have a Mopar Performance crate motor intake with an Edelbrock 750 carb, and I swapped in a 6.1 cam before I put the engine in my 70 Cuda. I'm very happy with the setup, it runs great and is trouble free. I haven't done any tuning on the timing curve, I'm running what was programmed in the Hemi6 from the factory.
