> You can already unlock additional power in your ECU by going stage I, II or III with custom and reputable ECU modders and the car feels completely different.

Yup, especially since that many cars artificially limited to "segment" the model into more models but are basically the exact same car. Some ECU modders, at least in the EU, also play it fully legit: they'll reprogram the ECU so that you've got more power and they'll help you with the paperwork for the DIV / insurance so that it's all legal.
