Guys problem solved.

I was under the impression that it had to be 43.5 PSI or above with the manifold pressure reference connected. Turns out it's with it disconnected and here's my test results. (i actually have more than i need lol.)

Vac disconnected from FPR : 3.3BAR ( 47.8 PSI )
Vac connected to FPR : 2.7 ( 39PSI )
