    What's up guys I have a question about my Bugeye wrx. It's stage 2 tuned via accessport, Cobb short ram intake, invidious bell mouth, hks turbo back. Ever since I got the car a few years back it would randomly only run mechanical boost and then return to normal operation when I would turn the car back on. Well over the past week it's only been running mechanical boost. I at first thought that the boost control solenoid was bad, but I reflashed the ecu before trying to clean the bcs out and problem is somewhat solved bit I'm only getting about 12 pounds of boost, wastegate duty maxes out around 80% and boost doesn't seem to build as smoothly as it should. I got this td04 from yerrow about a year and a half ago and am not too sure about the history of it. Any input on what I could do to improve my situation is greatly appreciated!

    So are you still running a Manual boost controller? Or an Electronic? All I know was that I struggled with my boost for years with an electronic one and as soon as I switched over to a manual....no issues lol.

    It had a manual boost controller on it when I bought the car, but I immediately threw that pos away and have used the stock bcs since lol I wondering though if this td04 came from a different year. I believe the restricter pill is different sizes for different years.

    it's possible the waste gate could be sticking.. could run some seafoam cleaner through it and see if it helps. if not possible spring tension going bad.
