I have an ACCEL DFI Gen. 6 standalone. Bought it from a fellow member on here and have decided to go with something else that is plug and play. This system has to be ran through the firewall and to individual plugs ( it is like a whole new harness). The the plugs are still connected to the harness and everthing works, it also comes with a 3 bar map sensor already connected. Looking to get $600 obo, let me know whats up, i'm located near Chicago.
