Anything would help, but the stock TMIC isn't that bad IMO... Just pay close attention to optimizing the flow through the stock tmic. I'm pretty sure you can get a fmic to cool much worse than any tmic, just by having improper airflow... I know my Perrin fmic sucked at the track due to the pressure issues I had in my engine bay. Meanwhile there are tmics like the process west tmic that handle gobs of power simply because they have a well designed splitter.
Make sure your stock tmic is sealing really well to the splitter without having any rows covered up and that your under tray is installed... You can probably get more use out of it than you would expect.
