Why is my speed limited to 80mph

I just bought my new 5.0 and my car tells me hat my speed is limited to 80, is that because of the fact that its a new engine? Or maybe because the dealer said it was built for 87 octane.


It's not a car, It's a legend.

The dealer lied to you. While you are stopped, use the three buttons under your headlight switch to get to the system info screen (should hit the middle one once). It will tell you towards the end of the car status how many administrator and/or mykeys you have. If you have any mykeys, make them admin keys. Unless of course you feel the need to control yourself.

There are 10 types of people in the world. Those who understand binary, and those who do not.

Lol...sounds like the dealer didnt take it out of "valet" mode. You gotta take it back to have them turn it off I think...could be wrong.

Are you saying the car won't accelerate above 80mph? Did you buy from dealer stock or did you order yours? If it was from dealer stock the dealer may have set a top speed limit to keep test drivers from really opening it up. If you check your manual I believe there is a way to set the top speed, a sort of parental control setting. Check it out and see if that is what is causing it.

Do I need to keep it there for any break in period? I've heard both ways that there is and isn't one.

There is no break in. Sounds like you're using a mykey that was programmed for Valet mode. Check your user manual on how to reset this or just try using the other key, it might be the admin key.

My key is a parental control system that keys you limit both the top speed and the top volume of the stereo.

Read your owners manual.

The changing of the key did the tick, thanks everyone!
