What kind of pipes do you have? Just curious. I recently installed the fuelpak and the recomended code I was given makes my 1.75" rush slip-ons pop and kackle a lot during deceleration. I'm awaiting a reply from Vance & Hines about this. Sounds kinda cool but I don't know that it's good for the engine or not.
no,it is not intended to use without the high flow a/c.. it will cause your bike to run extremely rich, you are better off not installing it until you do the a.c too..
