All cars sold in California(after a certain date , I am sure) have a limit of 155mph. Even if I bought a Vette like yours, it would have the same limitation. That's because they don't wan't vehicles going faster than the police around here. LOL. Everyone likes to take the police on a chase around these parts.
I don't even know if I want to take off the limiter because at 145mph, it gets scary.
