But if you want to do any kind of tuning, OBD tuning (or direct reprogramming of the internal maps) would probably be the safest way. Piggyback boxes will make the engine run with less control, as the engine management is being fed wrong sensor inputs, and the outputs are manipulated on the way to the actuators.
