Thanks for stating the obvious. Top speed fluctuates instead of reaching its max with the speed governor (intake restriction) for variable differential settings.
Intake restrictions restrict the amount of air coming into the engine thus reducing the power of the engine, not restricting it's top speed by electronics
uhm doesnt matter the less power the means the car wont actually get to tht speed thts y the veyron needs all tht 1001hp to get to 253 or w.e the top speed is cause on every stupid site its defferent lol
