Basically what I'm asking, is the restriction to 280HP to do with sofware of the ECU or is it hardware related which means I would have to replace the turbo's with steel ones as well as increase injector size along with other mods?

This is a turbo car...just turn up the boost and make as much power as you want. Be sure to run 93 octane at less than 16psi and add 100+ octane race fuel at more than 16psi. When you hit about 425rwhp, you'll be maxing out those injectors.
