HomemadeTurbo - DIY Turbo Forum

I finally got all the parts for my turbo setup except the fuel comp. I'll be buying either the s-afc or the v-afc tomorrow. I was up at millenium autosports today and someone told me the s-afc was better to use for the hack because it was better at controlling fuel, but i thought the v-afc was the same thing with a vtec controller. Now I have a vtec motor, and I would like to have the vafc for that purpose, but if the s-afc is better for turbo, I'd rather have that one. So anyone know the difference? I'm tryin to get this all done before march 1 cause its the first day the track is open :-P Thanx!
