They both manage engine performance. The Xede and CP-E Standback both intercept signals to the ECU and currently require installation, while the AP re-writes the ECU directly and plugs into your OBDII port. I don't have much data for the actual performance gains from either EMS, Xede claims gains of
66HP and 80 Torque stock. Since the AP isn't out for the MS3 yet, I'm guessing 25-50HP. And I don't have much data for the Standback, but it looks like 20HP from what I've seen.
