v-afc

I have a 97 prelude with just a aem intake and a apexi dunk cat back for right now. A buddy of mine is selling a v-afc for dirt cheap and i want to pick it up. What kind of power if any should I receive from this.

From what I hear you could get a decent not a lot but some more hp. I read somewhere that off all the vtec engines popping vtec early helps preludes the most.
