Green Map Remapping Milngavie. Our Green Map remapping in Milngavie is written for drivers doing the miles. We flatten the torque curve low down so the car pulls in a higher gear, cutting fuel burn on motorway runs, school runs and fleet work across Milngavie and East Dunbartonshire. A typical 8–15% MPG improvement when driven sensibly, with smoother, more relaxed low-rev driving as a bonus.
