The job of the power commander is to add/subtract fuel where it is needed, an auto tuner isnt going to lean out the program necessarily. Check your plugs and see what color they are burning. Obviously if they are black its too rich. If its burning a nice golden brown, then thats what it needs. Have it dyno tuned and tell the tuner that economy is a concern. Gas, however, is way cheaper than an engine rebuild.

I've been told the autotune is only needed if you are making a lot of changes and not all at once. It will save you tuning/dyno time. You also will need to put O2 sensors back in for autotune so make sure your exhaust has ports for these.

Gas Mileage
Only change I've made is the FatCat exhaust, no stage 1, bike runs around 200 degrees and consistently gets 45-48mpg. I kicking around the idea of going with a tuner and stage 1 but don't want the sh%tty mileage that seems to go with it.

Just curious, what kind of mileage are you seeing?

I'd have to bite the bullet and have it dyno'ed to see what the readings are.

The techs at power commander are pretty good about steering you in the direction you need to go as far as map choice. I'd suggest giving them a holler before you invest in an auto tuner or dyno tune for a custom map. There are places renting auto tuners too Ive heard.....might be worth the research to see what thats all about.
