I partially flowed my throttle body by smoothing the lower inlet and outlet side. There is still a ~6mm flat in the area below and behind the butterfly. I still want a quicker response earlier in the throttle movement. It appears that the most gains can be made by removing throttle body material around the trailing edge of the butterfly. Is this the general opinion for this mod?

Thanks

if u do this it does give you more responce but also u idle higher

y will it give a higher throttle ?
if the butterfly is closed its closed shouldnt be any extra air goin through ??

higher idle is what im after :) and better response.

TWUNKA you were gonna do my TB but i havent heard back from u yet, need a good date.

if the butterfly is closed its closed shouldnt be any extra air goin through ??

I think people are getting higher idle because they might had taken a little too much off the lip (possiblly letting a tricle of air in).
