Alright m8 welcome, it will click when you apply 12v, when you blow through c port it should only come through the w port, as the r port is a vent, if you blow through c port put finger over w port it should only, very slightly come through r port. I personally would not advise you to run a bleed valve as this is just tricking your ecu to run more boost and if you dont have the fuel to match this (MELTDOWN!)
