If that convinces you to spend $250 so be it. I don't think it's worth it.

Stock: 20.5735 in^2
BBK: 21.2114 in^2 (0.6379 in^2 larger than stock)
CFM: 21.8591 in^2 (0.6477 in^2 larger than BBK)

Yes I am aware of the minimal size difference. SVTs are know for there slow throttle response (it drives me crazy). I have been doing some research and people who upgrade the throttle body have a noticeable increase in throttle response. Apparently the stock one isn't the greatest design so I was looking for any opinions on it.
