will still be running vaccum just after market coz it wont run off the standard twin turbo set up Im not sure about ecu shudnt need to change as not doing injector or any fuel side at this point
theres some threads on there that detail the process you need to follow. Be wary that some of the wiring that goes into the vaccum box (black box) is for your map sensor and boost control solenoid which you will need to retain. You also need to change to a WRX or aftermarket ecu (ie. link) as your twin turbo one will throw codes because its no longer connected to the twin turbo setup and the car will not run
