Injectors are used, but not by me. -$120 shipped- SAFC is brand new (and includes everything you'd get if you bought it new.) Picked it up from another 2gnter about a month ago. -$180- I had to buy a boost-screw/plug from the hardware store, just use a hex key to adjust it. Ive also got a FMU disk/plate/gasket kit to change your FMU to 4:1. -$10-
