A piggyback physically plugs into the DME in the car and alters signals to achieve desired results. A flash reprograms the DME logic/tables to achive desired results. It's normally done by using either the OBD2 port or a "bench load" where your ECU is mailed to the flash supplier.
FOR THE LOVE OF GOD do not ask which is better.
