The stock boost control solenoid may work with a restrictor pill and with some wastegate adjustment. I'm not 100% positive until I try it on your car.
Worst case scenario we use a 3 port after market solenoid(runs around $80 or less). It is also possible your existing aftermarket solenoid can be wired and used with the stock ECU. Most boost solenoids are the same two wire setups.
