I took my 2012 SRT to my dealer last week for the annual state inspection, and he told me that there were five module software updates for my vehicle. I mentioned that I had done all the available recalls and technical service bulletins, but he pointed out that these five updates were NOT recalls or TSB's. They are NEW computer software updates that improve upon the originally installed factory software.
The updates are for engine management, transmission, suspension, braking and one other module (I'm not sure which one). I was skeptical that these updates would produce any noticeable improvements, but I was wrong. The engine now runs smoother and quieter, and has a more aggressive power curve. The 5 speed transmission now produces silky smooth shifts, with barely noticeable shift points. The suspension is less bumpy, and the braking seems to require less pedal pressure.
The acronyms for the five updates, which your dealer will hopefully recognize, are: PLGM, ABS, TCM, ADCM and ELSD.
The number of updates available for your vehicle will depend on the VIN. Also, if you have not exceeded the basic factory warranty of 36,000 miles, these updates should be free. If you are over 36,000 miles, your dealer might charge about $20 for each update.
My beast is a very early 2012 with 40,000 miles, so it was really worth this small investment. Good luck!
