Tru-Boost has it's own boost solenoid, so you can use that as your EBC. No need for Hondata EBC then. As for tying it in, IIRC you need to so KPro can use it as the boost control. You need to get the correct pins from Hondata and plug into your ECU harness (For 06-11 Si's anyway). I assume it's the same for you.
