HARTGE announced today that they can remove the top speed limit from the BMW M3 E90, E92 and E93. HARTGE can remove the top speed limit of the BMW M3 with the help of a reprogrammed ECU from OBD than can take the maximum speed to 340 km/h or 291 km/h. However, attention must be paid to the speed index of the tires you're using. If you're not sure about that, HARTGE can provide a set of Pirelli P ZERO tires that can cope with the 340 km/h top speed of the modified BMW M3.
The price for the HARTGE top speed modification has not been announced.
