Arent these japan spec ecu's designed with a certain level of entry modifications? From what i understand your stock ecu is good enough unless of course you have some crazy mods and are looking to boost higher. But the question i have is- wouldn;t it be safer to go for a programable unit considering the fact that these preprogrammed ecu's eg. mines are preset in Japan according to cars spec sheet and the prices imho do not justify me simply plugging in some preprogrammed ecu? pls explain?
