SPEED LIMITER DELETE & DEACTIVATION

The limiter is often applied as a gentleman’s agreement amongst car manufactures or by customer choice e.g. Most BMW and Mercedes vehicles have a factory set speed limiter of 155 MPH / 250 KMH. Fleet vans such as Ford Transit’s have speed limiters set to 55/70MPH which we can remove completely.
