Throttle body and Injectors

I have an 09 Avenger SXT with the 2.7l V6. I've done exhaust and CAI so far but the throttle response is crap with this car.

I've been talking to a lot of guys and most recommend upgrading to the Charger throttle body since its bigger and a direct fit. Do you guys know if there are any for the 2.7 that would be better?

Also, any ideas on injector upgrades?
