The Mopar PCM has a "performance" program built in. The JET chip
modifies the signals that the PCM gets, tricking it. After a while,
the PCM will learn what the JET chip is doing, and re-tune itself to
compensate, removing most of the performance. Then you'll need to
reset the PCM back to factory defaults to regain the JET benefits.

Check the part numbers. I've seen different P/Ns for most
years/drivetrains. Plugging a '98 isn't guaranteed to work on a '99,
and if your state inspection checks CARB numbers, emissions, etc. you
may get nailed.
