You won't need a boost control solenoid as you should have a 3 port item fitted as standard. You may need to change the MAP sensor though to get over 1bar of boost without it throwing up a CEL and limiting the boost to 0.5bar. This is part of the Apexi boost control kit which also includes a boost control solenoid.
