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....
To all respectable altezza member here;
i need some opinion for this matter, what after market battery is available for altezza? I try to find the factory specification few years back ( 55D23L ) but no avail...
