??? wastegate setup

[twoboosted]

Ok I trying to hook up a mbc to my wastegate but it not working. First I tried hooking up just one vac hose to it and the boost stayed at 7 psi (spring in the wastegate). Next I tried two vac hose's one to the top and to the bottem Now it's balls to the wall either 15 or 25 psi (25 hit's fuel cut,bad very bad). Take a look at my pictures to see how I have it. Some please give me hand with this thing I'm just trying to get about 10 or 15 psi.

I thought that on our cars, your not supposed to hook up to the top port on the external only the side one. Thats how my HKS is set up maybe the Tials are different? The other line to your MBC would tee off of your BOV for a vacuum source.

Only use the side port on the Tial.
