Firstly, thanks alot for the replies. I don't intend to go management anytime soon, as major mods to my vehicle aren't really sensible atm. @JJ16 It's a 2 port boost solenoid. I'll post the images of the current setup. However, I came across an odd senario whereby the line from the MAP sensor (which is also mounted on the strut tower in the vicinity of the Boost Solenoid) is merely dangling. There's also a 'Valve Assembly-Solenoid' (which connects to a tee that links to the manifold) mounted right below and the line from the MAP sensor possesses apt length to just connect to it (the Assembly Solenoid has an 'unused port') so I'm wondering if it connects to there. Hope the attempt at an explanation isn't too abstract, and that the pictures clarify.
And yes I more than likely misquoted that stock PSI @Aaron 2NR. There seems to be no consensus however with some stating 'it peaks at 18 and tapers back to 16' or '17 psi from my untampered 1998 WRX STI' leading to my confusion.
http://www.type-ra.com/turbo.htm quotes the Type R as possessing 0.8kg/cm^2 which equates to 11.4PSI. I guess once the solenoid is working properly I'll truly find out.
