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....
any sifu can told me how to c & judge the injector cc or size.?
some of my frenz told me quite alot of the branded injector actually is also made by denso..
is that's true? EVO injector is 550 or 560cc? what's color...
