Pabably make it run worse.
If you have a bigger cam, better intake, and better exhaust, then a bigger TB would help. If your stock then NO.
The main componants a agressive engine are
Big TB
big injectors
big intake
Big Cam
Big valves
Big runner on the heads
Higher compression pistons
Big headers
Picking one of these will just make the car run bad.
