I had that same code back when I had an SCT device for my Charger.
Scratching my head though as to your plight, because IIRC, I was able to return the car to the stock file.
I eventually ditched the SCT & purchased a Diablosport device.
I'm willing to bet that SCT has the definition of that code, and/or it's work around. You think they'd have limited hours on a Saturday?
