The manual also is telling me my top speed is factory set at 80 miles per hour is this correct? Maybe I am not understanding the Manual.
You must be looking at the Mykey
settings: MAX Speed 65, 70, 75, 80 MPH or Off
The manual recommends 93 octane for improved performance. just like previous years.
