I figured that if all I did was smooth everything out and still had the butterflys the same size it really wouldn't flow significantly more. If the bore size isn't changed then the flow is still restricted, I understand cleaning out the paths and letting it flow smoother. What do these things do stock on the flow bench? If it really increases it by just smoothing everything out that'd be cool.
