Dual boost solenoids! According to Mitsubishi:

The ECM actuates the turbocharger wastegate solenoid 1 at a duty cycle rate that suits the engine speed and throttle valve opening angle, and actuates the turbocharger wastegate solenoid 2 at a duty cycle rate that suits the engine speed. By operating a combination of two turbocharger wastegate solenoid, the ECM is able to control a wide range of intake charge pressure. Looks like they are after a flatter boost curve too.

AEM has one CAN Bus EMS working now, is cracking the STi now and has the EVOX next on the development schedule.
