I have an SCT for the Magnum 5.9 in my Dart. I'm not afraid of tuning the fuel but spark scares me. I'm afraid I'm going to blow it up by pushing the spark too far.
Definitely in the same boat there. I was hesitant to stray too much from anything already out there until I got the knock sensors in the car. Granted, you still have to configure the sensors, and mine might not be configured sensitive enough to catch the first knock, but at least it's some kind of safety blanket.
