I realize the size is overkill for a 2.0L 210-220whp engine, but I like the idea of having enough injector and not worrying about maxing them out while dyno tuning... Would there be any real advantage of going with a more appropriate sized injector?

 

Correct me if i'm wrong, but if they are too big, they will cause for a bad idle. I think it has to do w/ the injector pulse flowing too much fuel when not at higher RPM's. What's your stock injector flow rate? It's prob. not enough to cause any huge problems...
