The MP orange box pulls timing out above 4000 rpm , really a poor choice for an ignition box , swap it out for something better .




If its an old orange box it may be ok. I bought mine about 1999 or early 2000. It works good and dont pull timing. In fact it was on my sons Dart and when we put MSD on it the car ran no faster and ran no different. But it seems the newer orange boxes are giving some trouble. How new I dont really know all I can tell you is mine works good and its about 14 years old. Most people who run the chrome box seem to say it works good for them. I would think in good tune you can get in the high 12's with some hook. Good luck , Ron
