Slant 6 Turbo 68Dart Project

I cranked the screw all the way in. I looked up the aeromotive copy I purchased, and check this page out. I think I found my problem. Check the baseline psi... http://aeromotiveinc.com/products-p...gulator-adjustable-efi-2-6-inlets-1-6-return/ Also the gauge I finally looked closely measures in BAR, what a stupid mistake...

The version I actually bought lists it as being adjustable from 0. Would there be a difference in switching my in/out ports? The bottom is very obviously the return. I Allready found that one out. I want to know how well that nickle valve works. But essentially I got a non-functioning car at the moment to even start testing boost parts on... this sucks.
