still stock injectors. I got the rails just to make sure I am still in the "safe zone" as far as fuel delivery. The techs at Pauls were telling me that at high RPM's the rails aren't a requirement but it ensure that fuel delivery won't be an issue. Others have said I don't need them at all. I don't have the equipment to fully test the fuel flow/rates so I figure i'd rather overdo it now, than pay later. Bradenton?? I'm planning on being there.
