Buggymaster told me that I would only gain about 2 MPH on the top end. I'm confused.

i did not get any rpm gains from my cdi4650@36mph,stock was the same.it did make more power but not rpms.rpms come from moving more air the more air you move from one end to the other the more rpms you will get.if you got a bigger header and mufler you will get more rpms.then you will need to rejet again and even more rpms and on and on.air=rpms
blow through a small straw and blow through a big straw and you can see how much more air will go through.
