For my next project I'm going to be using a smim. I'm using it primarily because its easier to set up for Rwd. It's runners and plenum are very large compared to a stock cast unit. They are however not as smooth. This is still however a street build and I don't want something with zero power below 3k.

I have 3 different stock size throttle bodies I can use. If I use the smallest one, from my mighty max, Will it be more responsive in the lower rpm range?
