I would of said if ur run the arrow the wrong way u get unlimited boost until turbo explodes or somethihng like that? Cause it wouldnt let pressure through the line? Dunno for sure but if ur still running standard it would most likely mean you have installed it in the wrong place, i.e the facotry solenoid is working around it. I would turn the valve back to lowest and put the tpiece in between the possitive pressure line (sr20's it comes from cooler piping at front of engine bay, ca18 its the hose on the compressor housing above the intake pipe) so the new tpiece goes between positive pressure line and the old tpiece that goes to actuator and solenoid this way it will bleed around the factory solenoid or so i have heard. I hope this is right if anyone else can comment? white180sx will know cause he has bleed valve actually a post similar can be found here

where white180sx tells how to install bleed valve. DDont read anything i wrote cause its to do with electronic boost controller, but white180 talks of a bleed valve
Hope this huge text helps :p and this pic
if its sr20 it will look something like this
if you want an actual picture i can get one but this should be sufficient
anyone else can tell me im wrong if i am cause i dont wanna be blamed but pretty sure this is right
