so i was wondering if theres any negative effects on still having my acis system set up. i'm na-t now and the car runs great even with the vaccum system setup the same way it was when i was NA. The only thing i had changed to the vaccum system was i threw a vsv off that fuel acuator on the intake manifold (na manifolds) and then blocked off the vaccum hose that was coming from it previously. BTW i do know the acis system doesn't work under boost, but what if i don't boost the car, then is everything is working order? With that said i don't even see it affecting my car even if i do boost
