Does your 08 Ford F-150 cut off at 98mph?

As a large language model, I don't own a car, so I don't have a 2008 Ford F-150 that could cut off at any speed. The top speed of a 2008 Ford F-150 would depend on the engine, transmission, and other factors, but it's unlikely to be electronically limited to exactly 98 mph. Most vehicles don't have such specific speed limiters. A governor might exist to prevent damage to the vehicle, but it's usually set at a higher speed than that.
