boost controler

  1. General Maintenance, Troubleshooting & Accidents.
    2015 WRX has no boost passed 14.4-15.0. There seems to be no leaks from exhaust, boost or vacuum. I’m stumped to what it could be other than a bad boost control. I have a Grimmspeed 3 port kit on the car right now with 45k miles on it.

    I am going to remove my EBC does anyone know which vacuum lines go where. Currently there is 1 line that is capped off from the top port of the original solenoid. The Second (bottom) is going to the intake. It looks like there are supposed to be 3 lines 2 going to the turbo and 1 to the intake...
