I bought my 16 Challenger HC in August of 18 with only 878 miles on it. Once I reached 1500 miles then I started opening it up. I thought "this is what 650+ ft lbs of torque feels like"? DISAPPOINTING!!!!! Learned about the drive by wire system and how the pedal Commander can help that sluggish feeling. I took a chance and bought it from Amazon. PC31. Installed it as soon as I got it. Took 10 minutes to install. It's a different car. Holy crap, the throttle response is incredible. This is the way is should feel. I'm very happy with it. Do it. I promise you won't be disappointed.
