If you add just a piggyback ECU (hell, any ECU) and don't upgrade the internals, you won't get much out of it. You add bigger injectors and a clearer header, you might get an additional 10-15 hp... change the exhaust and you get yourself that last 15hp that the ECU claims.
Make sure to look closely at the ECU descriptions and never assume that Programs will give you that much more output without doing something to the fuel system components first.
