There are various SCT options through Hemifever. For $260 you can get three canned tunes you upload yourself or you can get the more expensive option where you get custom tunes. For a basic motor setup, I'd get the canned tunes. For a heavily modified D, I'd get the custom tunes.
As indicated above, there's no point to using the Mopar Perfomance PCM because the SCT program will overwrite the program in it. In addition, I'd wonder if the SCT would work with a Mopar Performance PCM, Superchips and Hypertech can't. In order for these programmers to work, they have to "recognize" the existing PCM program before they'll upload their programing. People have had issues with Hypertech/Superchips not recognizing factory updates to stock PCMs and the Mopar Performance PCM has different software programing from a stock PCM. Maybe SCT is different??
That's why I was a little leery about that eBay auction. The seller indicated he might have used a Hypertech programmer on the Mopar Performance PCM on his modified Durango and was selling the Hypertech programmer and the PCM together because he didn't know if the Mopar Performance PCM had the Hypertech program in it. I was a tad suspicious because, if he has a clue about his alleged "modified Durrango", he'd have known the Hypertech programmer wouldn't work with a Mopar Performance PCM. Maybe he did or didn't have the vehicle. Even so, maybe it was a good deal for a PCM and a possibly "VIN LOCKED" Programmer.
Greendurango, I may be interested in the Mopar Performance PCM (or may go SCT myself) but I'd first like to hear what it does when you install it.
