Vmax stands for 'speed limiter'.
Most cars are limited to 200-250 km/h while some cars can reach a top speed of 300+ km/h.
As the name implies, we as tuners can remove the speed limiter that manufacturers introduce in many cars.
99% Of the cars currently on the market are equipped with the deactivation of this limiter.
This speed limit is handled by simply sending the read file to us, which we can disable.
