Default jdm intake manifold question

I was wondering if anyone knew whether or not you get any extra power if you take the butterfly valves out of the intake manifold??

You will lose low end power and gain nothing on the high end.

^well those butterflys open up during high rpms

so taking them off is just like them opening in the high rpms....

they close on lower rpms. so if they are left open all the time, its not optimal and you will lose power

you can tune around the power loss. I sure as hell havent noticed any low end power loss.
