You'll be unbanned on 21/05/14. If, when you come back, you still have your mod you will be banned for much longer, so be sure to remove it and any others that alter the way you move when playing on here. As well as giving you an unfair advantage in parkour races, your mod could also make it possible for you to climb over walls that aren't meant to be climbed over or reach checkpoints in the air that shouldn't be reached without a car.
