Has anyone tired the larger throttle body with the smaller housing? I thought I had it configured like that temporarily for some reason and the car felt very torquey. Like the the larger opening followed by stepped housing focused the air more efficiently in my N/A car. I now have the larger housing as well and the car runs great, but for whatever reason, the car seemed to pull harder when I had it the other way. Since then, I have added the NW SCAI and the car is reliable, code free, and I did the install myself. I recall learning that with a forced induction motor, less restriction meant more output. Im wondering if anyone has dynoed the car both ways?
