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?

 

It needs to be re tuned Without the cat and ex changes it F's with the computer

 

I'm planning on getting the Hypertech Max Energy Programmer to tune everything before I do.

I didn't remove the cat.
