Right I see you're going very low boost. I don't know a huge amount about going down the 5th injector route, But iirc you'll want to be very careful about running it lean. You'll defs need to get it mapped, you'll kill it in no time running it Lean as the fuel won't be there up high. Plus you'll need to map the 5th injector in.... I'm not sure wether youll need A stand alone ecu to do this but would imagine you will, I doubt a fifth injector can be mapped into a stock ecu...


a 3bar map sensor is what most people use as it gives the edu a boost reading so it can adjust the map accordingly. Without one your ecu will throw a shit fit and not work. That's the only way a stock ecu can be used with the supercharger conversions done by lynx, they leave the stock map sensor in place on the throttle body pre-charger, so it doesn't see boost and thus still operates!
