Is remapping better then chipping?
OBD remapping is the modern technique replacing chipping. It reads and writes on your ECU via the OBD port and does not invalidate warranties. Chipping your car requires opening of the ECU and installing a preprogrammed chip which is a fixed one map suits all. They do not take into account other modifications and can not be mapped to suit particular requirements. This is not a resistor that fools your ECU, it is the genuine article.
