Hi, I am currently in the process of supercharging my 2.0 8v mk3... Just wondered if there was anyone on here that could tell me what else i will need.. i have the following already; Eaton m45 charger 4 branch manifold and new 2.5" exhaust system 440cc bosch injectors G reddy universal blow off valve Pipercross viper induction kit The main question is really, What else do i need? and what to do with the standard ECU? should i get megasquirt or just tune the standard ECU? Many thanks lewis.
