so if i understand how this works, it can be used on a boosted NA protege with the stock NA ECU?
Yes, but you also need a FMU, like one from BEGi. You need a device that will give you the added fuel under boost conditions.

It stops the stock ecu from pulling fuel (lean condition) when you go into boost
