Right now i have a Plog, 2 1/2" catless DP, Taylor 8mm wires, SLP cold air ram/ram air, MPS with 3.6 is on its way with plugs also. Headers may come later but this is as far as im going for now, im getting it tuned soon but im thinking about going with an aeroforce interceptor scan gauge next, how hard is the instal for one of them?
