lancer_ajai2, yes i'm using the diagram on that web site and i'm not using any piggyback just afr to increase the fuel presure.... but i think better use afc or change to bigger injector coz high fuel presure not healthy for fuel pump....
Currently the double signal button malfunction after I open it up. I tried to put it back, but it doesn't work after that. Please show some proper instruction to fix it please ><"
