I dont follow you because both the blue and green lines are pressure sources coming from the turbo. The green is around the compressor housing and the blue is at the throat of the turbo. The blue is smaller and carrys a less volume of air meaning that less of air hitting the wga flapper and less deverting of exhaust gases. I dont have my stock solenoid (stock bc) hooked up. Every vaccum line is gone. Just unplug the blue line and cap the solenoid. Then place a 5/32 over the blue line to your mbc to the wga. Cap that green line. Just try it you will be surprise like I am.
Trust nothing will happen if you T in the stock bc. I had my boost source for my fpr T'ing in the blue line before I switch over to it for my bc.
