A re-map is programmed thoughout the rev range under different loads makign sure the cars is running its correct amount of fuel for the conditions.
So a remap is a more correct way of tuning an engine right? The only advantages with a box is that you can unplug it before taking the car to service and that you donīt run the risk of the extra power being wiped out if the ECU should be reprogrammed?
