so i have the greddy tvvc manual boost controller and i have it hooked up correctly(as far as i know) according to the arrows i have the manifold vac to the in arrow and the out arrow is hooked up to the wastegate actuator . but if i turn it almost all the way to the up side on the dial it won't go past 5psi . what gives does anyone have any ideas on what's up with this thing? i don't think that it could be broken damn it cost about $200 it shouldn't be broken

- i need feedback from you guys
later

 

also if anyone has the manual for this can you post the installation instructions from it
thanks
