If you attempt to use launch control you get a message on the display that it's unavailable until you reach 500 miles. I've also read somewhere that the engine limits power output until that mark is reached.
I picked up my Green Machine on the 11th of April, getting close to my break in, so I can't wait to start letting it go more! Like the OP, I had come from a '11 RT (Toxic Orange, I miss that color) :cool:
