There would be no power gains really. The only possible benefit that I could fathom is maybe slightly quicker butterfly actuation.

I just picked up a 1zz throttle body for my Yaris. That's the only real throttle body gain I've heard of for these cars so far.

From what I was reading up on, there can be some benefits to polishing the throttlebody, but usually when porting it a bit also. It had to do with removing any imperfections and opening the entrance a bit. Mostly trying to just remove the step as the air enters the TB.

That being said, even doing that on a factory setup probably won't net any benefit, with an intake and exhaust possibly, with an all out build I would imagine that it would help squeeze any hidden potential out of it.

Then you did something wrong because low end is greatly improved with the 1ZZ TB.

if you swap the chip you should have no issues!
