Hi everyone, can someone enlighten me on what this is on my gf8 sti? Looks after market and says Rspec on it, got no idea what it is. Cheers :)

Is that located near front wing above abs unit ?

Yep 

Barke ballance controller ? Clutching at straws

I would say It's a manual boost controller

Looks like vacuum pipes are attached to it and the boost solenoid in the background doesn't look like the bottom port is attached to anything .

so id say manual boost controller ;-)

What boost are you running ?
