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?
