normally a 5 port mill will give you more low-midrange torque and power and not as much on the top, as for a 7 port it will give you more on the mid-high end power band and not as much on the bottom. if you are considering that new rossi plus 7 tb hot mod it will have plenty of low end snap to it thats what rick at fusion motor sport does with those mills that thing will fly!!! if you buy it use the rossi 9886 pipe and a long manifold that combo will help you with bottom end and still have great top end. hope this helped. good luck.
