  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.
  2. Engine Modifications
    I was just wondering if anyone is running a lightweight pulley and if so what brand and if they like it? Also i have heard from a few people that they can be bad for your engine in the long run?:confused:
