So, after much stuffing around I have gone back to e separate dawes valve (DV) and dawes needle valve (DNV) . There was no way that the GFB unit was going to work. The dawes set up works fine its only the extra tubing that the installation involves that i was trying to eliminate. One thing about the GFB unit that concerned me was that when I used my lungs to blow into it and turn the adjustment the boost rise never actually turned off. The air would be diverted and come out the boost ports? Weird. I thought that they were two separate valves. Perhaps not.
