Hi all, just picked up a 2013 ZL1 last week. Only 10K miles on it and got it for a great price. Unfortunately I cannot go over 85 mph no matter what. It tells me speed limit maxed. Been trying to find out all over how to fix this issue. Also noticed that I can't change my driver settings on touring or sport. No light or change that I can notice.

any suggestions on fixing these issues? Awesome car, but challenging when trying to pass some cars on the freeway..

 

A worried father had his sons car limited? You will need access to a higher end scan tool. Its is just a setting like tire diameter or rear gear.
