2000 magnum

Magnum engines don't have knock sensors. That's one of the reasons the factory tunes were so soft. Later models had even softer tunes and some 2000 and maybe other years go a soft tune as a service campain. That would have a sticker on the radiator support or the PCM itself. Don't remember if that reflash was all v8 Magnums or just the 5.2 liter. Some call it the death flash because it killed power. Supposedly it was a bandaid fix for the intake plate vacuum leak that caused a lot of spark knock in some of them.
