Hello to all, i'm posting this question for my son. He has a 1988 5.0 mustang with the mass air upgrade and a vortech super charger. He just installed a trick flow intake also. He would like to know where do you route the pvc hose to? what fitting? when he installs it to the new manifold it runs really really bad, almost sounds like it has a wild cam shaft and almost wants to stall out. When he disconnects it and plugs the manifold fitting it runs just right
