If you have the 4Di system you should be able to connect a laptop computer to the FI computer and watch the various sensor values and injector settings. Watch the O2 compensation value to learn how close to optimal your fuel map settings are.

jhaynie, at what engine temperature does your system go closed loop? I've got my 4Di set fairly low (160 degrees). The engine warms up pretty quick to 160, but the engine also acts a bit "cold" before it warms up. Still, it's *much* better than carbs!
