Its been a while, does anyone have any expierence with the portfueler system available through hahn racecraft? It tricks the map sensor using their "fuel mapper" and keeps the stock injectors as primaries. Then runs a second set of 500cc injectors and jsut dumps fuel. im guessing its tuneable using a wideband and you just have to adjust the amount of fuel dumped to get the right a/f ratio.
