piggyback controllers are a proven solid method to tune beyond the factory ecu - some attaining outstanding performance. It is a steeping stone towards a standalone... but in reality, most are quite satisfied at this level and go no further. SAFC is probably the most popular tuning item ever sold... at least here in the west. U guys down under have the options with standalones tho.
