I got given a turbo for my r33 thought it couldnt hurt to try is but anyway having trouble getting boost controller working on the turbo there was a vac line from the actuator and turbo so put a T peice for 1 end and other end is on the manifold I can only get 10 psi no matter what I do I've tried fiddling with the hoses and the boost either keeps climbing or it gose to what I set it at then it drops as fast as it climbed how can I fix this
