Hey guys. So I am curious to know the top speed of everyone’s challengers. I have a 2017 r/t manual 6 speed and an unlocked pcm. With the stock pcm top speed was 140 before it would shut down. Tonight I wanted to push it a little further and got 160 in 5th gear. It was still steadily climbing but I backed out because my exit was coming up. Are these cars capable of 180+ with stock everything besides and unlocked pcm like mine?
