thanks Kev, I'm been flowing your work and posts on forum 
        
 
         correct me if I'm wrong, fuel mod can be done with your mod kit or power commander? i think i read somewhere that 2009 XT has something changed so its really good in auto balancing fuel - again maybe I'm wrong.
        
 Or all i need to do is to flow this tutorrial ?
