I recently installed one of the e-bay manifolds and it has created a lower vacuum. Before the instal I was running about 17-18 In of vac after i put on the manifold I am running about 12-14, will the increased air flow cause this? or I am looking at another issue. I have smoke tested the new manifold and there are no leaks. sprayed the IC pipes that i removed with brake cleaner and nothing there, any other possibilities?
