No animosity here, it's just important to note what is (or what isn't) available/useable out there. Understandably there has been real changes over the years so there is alot of confusion/misinformation that gets passed around.
All companies (SC, SCT, Diablo etc) base everything by the PCM # because Chrysler has a bad tendency to mix n match from year to year. PCM # not only indicates what "language" (JTEC vs JTEC + vs NGC2,3,4....) the PCM uses but differences in the code itself. I've seen a WJ with a WK (05) PCM and all sorts of goofy stuff happen.
