Celica Forums Thread Like Summary - Does anybody actually KNOW about an ECU UPGRADE?

Does anybody know about an ecu upgrade? Everyone acts like they know what they're talking about, but i don't know who to believe. I hear some people say they work. Then you got others that say they don't work. Both sides claim that they know from personal experience. Is there like an expert on this topic? If you really think you know... Answer the question. Cuz i do not have a clue...like most of the people who are writing about this topic. :thumbsup:
