Yeah, good. Just what I'd expect. You don't need those other things for it to run good.

However;
Only bones I have to pick is pulling the downstream O2s when they don't NEED to be pulled, AND can be used as a backup diagnostic tool. They also don't set codes when you solder in the resistor and Capacitor from the MIL circuit....making them perfect backup sensors for tuning. Believe me, I used them a lot to diagnose/compare upstream downstream performance and bank to bank performance.
And pulling EGR when it has no effect on performance but if kept installed can help reduce Nox emissions.

I keep anything that doesn't hurt my automotive goals. Namely my priorities are set as such:
safety->performance->environment->OEM driveability->fuel economy
