The ability to put an AWD into RWD by pushing a couple of buttons on the steering wheel is because of a device that I ordered from Zautotech. It simply plugs into the OBD port under the dash and it opens ALOT of the software already installed on the Chargers, 300s, some trucks, Jeeps and Durangos. It is by far the best "bang for the buck" upgrade that I have done. It has so many features that you can enable on your car, line lock, force RWD or AWD or auto AWD, light shows (which are pretty impressive themselves), add sport mode, open all the SRT pages including the ones in the EVIC and on and on. I travelled 300 miles to buy my car, and it was well worth it. My 2014 R/T AWD Max was loaded with every factory option except paddle shift and sport mode. I added sport mode with the Zautotech Tazer and the paddle shifters are unnecessary in my opinion because I can manually shift using the shifter in manual mode or I can change gears using the cruise control + or - buttons on the steering wheel. I bought my car with 34000 miles on it for $23100.00 at a Dodge dealer in Troy Michigan on a Saturday afternoon and drove it home to Erie Pa. that same night, the closest I could come to finding an equally optioned car around here was at least $27k and I wasn't paying that price!! I have upgraded and personalized the car the way my wife likes it and I think it looks pretty damn good considering what I paid and what I transformed it into since I bought it in March. I put an SLP Loudmouth Exhaust, LMI Frankentake cold air intake, 20" MRR wheels and General GMax tires, pinstripes, head, tail and foglight covers, Tazer, ventshades on the windows, Diablosport Intune tuner and painted the calipers all for less than $2000.00 by doing the work myself and finding the best price I could on the parts I wanted. The car runs fantastic and sounds great, not to mention the fun I have driving it. We are going to drive it to Elsinore Ca in Oct, then back home after a 2 week stay, and im really looking forward to the trip. I will include pics I took the day we bought it and some now.
