              Do u think adjusting idle and the fuel in the diagnostics will be enough for my setup or will i need the fuel mod?

         As I mentioned earlier, you'll be fine without a fuel mod/O2 controller, but you are on the limit regarding how lean the air/fuel ratio will be. The bike will run more smoothly, pull from lower down and generally feel much perkier with these two mods fitted.
         
        
 Not essential, but worth doing.
