this is what your missing.. your china spec shitbox TMIC wouldnt be more efficient than the STi one. Size doesn't mean make it more efficient, core and material with measured flow would be a good way to measure efficiency.

So, sell ur shitter TMIC from China, and go buy yourself a proper STi one.

Or better yet, don't listen to any of the advice that people have given you in the thread, go speak to your local garage (MMS, ASG, X-speed, who ever) and ask them if ur china spec one is better than an STi one, for example.
