Just got my first fuel injected machine and was wondering what exactly a "power commander" does. I believe you can adjuct the power curve? Also what do they run and are they worth it?

You need to mod the amount of fuel youre EFI engine gets after you have made mods like exhaust and filter. The standard ECU cant tell you have made the mods and will run lean. The EFI piggy back box fools the Yamaha ECU into giving it extra fuel and so you can get more power after the mods.
$350 for Power commander III is the best programable one in my opinion.
