Horrible gas mileage. Power commander?

[OUTLAW1300]

I am getting horrible gas mileage (around 25mpg highway). I checked the spark plugs and they are dark black but dry. This means its running too rich? I also have a full TiForce exhaust and the tip is black as well. Using 91 octane gas and ride 65mph highway. Is this bad gas mileage caused by the Dynojet PC3? If so where can I get maps for it? No help searching google.

And also what does the HIGH - MEDIUM - LOW buttons on the PC3 do? Am I on the wrong setting?

THANKS IN ADVANCE FOR THE HELP!

i had the same pro what i did i mess with te map from dynojet taking out fuel little by little and now i'm getting better fuel mileage, but the best thing to do is getting your bike dyno. i'm taking mine to the dyno when i finish with all my upgrades, another thing i did i cahnged the spark plugs with hotter ones that help out a little but i didn't like them, i think with colder plugs you get better mpg. i took them out and they looked just fine i wasn't running rich anymore the dark, black looked went away . that's my story my friend

Yup too rich.

The power commander can fix it.
If someone has a map they will post to you.
List all your mods so someone can help with the map.

It's too rich...you need a new map. It would be best to have a dyno tune.

Professor has a great starter map... Although it is best to have a custom map made, his is will provide you some economy as well as performance

Click the link below. Enter year & model of your bike and it will come up with a list of maps for your PC. What happened to me was I had the wrong map on my PCIII and a TRE, so it made gas mileage even worse.
