I am assuming you have N/A ( normally aspirated ) model since you didn't mention SRT6 ......
NO to ECU chips - all a rip off.
1. Needswings Single / Dual Cold Air Induction ( CAI ).
2. 74 mm throttle body upgrade
3. new set of plugs / wires ( Needswings also )
4. Eurotune
( I believe Rob (needswings) is also about ready to release the performance headers also )
O, and get an oil catch can
If you got BIG bucks, read the thread on here about Corky's turbo charger upgrade.
( in that order )
Where are you located ?
