Tempting and yes that would fix that problem if it's the factory boost solenoid. But I've sworn to myself that I won't go down that path again, "Manual boost controllers" They gave me non stop problems on my GC8 and even my Legacy had issues back in the day when I used one.
If its the factory controller I'll get I a EBC and probably do my Turbo/
ECU upgrade in a few months time.
If its the TD04 then hey.. Guess I'll be doing the above upgrade a little sooner than expected.
