Ok so I'm starting to get very very upset. I have a s13 chassis with an s13 sr20det swap. wiring specialties harness, GReddyt intake manifold and cold pipe, isis FMIC, HKS BOV, Autometer fuel pressure and boost/vac, and AEM wideband. The issue i'm having only started after I hooked up the vacuum to the FPR. Before I ever hooked up a vacuum line the car ran like a scalded ass ape. 10 PSI of boost, 20 enough vac under idle. Hooked up vacuum and put in a Aeromotive 11140 90 psi 340 LPH fuel pump. After this I started having fuel issues where as I get to 0 on the boost gauge , my fuel pressure falls flat from 42 to below 20 and the car starts to sputter. I removed the fuel pump and went back to the stock KA and still having the same issue. Removed the vacuum and still having the same issue. I'm needing some help.

And in advance I never saw more than 42 psi on the fuel pressure regardless of the fuel pump i was running
