I'm in the process of finally putting the final touches on my Stage 2 motor and have a few questions about a manual boost controller.  I ran a silicon vacuum line into the car with the thoughts I would install a manual controller inside the car but the line is quite long.  I blew through the hose, which is a 7/32 line, and it's awfully hard to blow through.  I can feel the air but it's nt exactly a smooth flow.  So, I'm wondering if this is going to be an accurate way to control boost?  I have a TurboSmart External gate to control.  I may try a buddy's manual valve he bought of Ebay and install it next to the turbo and see how well it does.  I'd really like to install and in-car controller though.  Any good ideas?
