i have a 2007 nightrain and bought a screaming eagle EFI race fueler (32136-06a) on e-bay. i was under the impression that i could use this item for my stage one instead of buying the more expensive EFI race tuner kit (32107-01h). has anybody used the race fueler i bought and done the stage one tune. did it work or have i made a mistake and bought the wrong bit. i have the screaming eagle stage one air filter already and will be buying vance and hines pipes.
