tooter's manifold adventure... - Toyota Yaris Forums

In normal driving it doesn't bog down like stock when you let out the clutch. and you can feel it come on stronger at around 3,000 rpm on up. The larger bore of the throttle body now better matches the increased flow abilities of the tooter. It feels lots more gutsy.

Now some of this effect is simply the fact that when you push on the gas pedal, the larger throttle body's butterfly is letting in more air for the same throttle position.
But the biggest difference is when the throttle is to the floor...
