Manifold pressure referenced fuel pressure for NA
Apparently Aeromotive tech support is recommending manifold referenced fuel pressure for NA because manifold vacuum will suck fuel out of the injectors. Is this really the case? I’ve never done this and I am guessing GMPP and stock tunes are not set up for this. I would think this would cause them to run lean and adjust fuel trims accordingly.
Carl? Donny? Any thoughts?
