Theoretically, yes. Although, I have found (on my bike anyway) that the difference is not all that great. I've ended up trying to map for best power in all ranges. Though I have a map switch installed, it is now an on/off for my AutoTune.

2. is the auto tune worth getting

Depends on a lot of things. Do you have affordable dyno tuning available in your area? Is your bike still (mostly) stock, or have you modified the intake/exhaust system.

I think if you have dyno tuning available and/or your bike is stock, then you don't need the Autotune. It turns out that it is a pain in the a$$ to create a map with it. At this point, I'm using it more for guidance than direct mapping.

3. does the sensor with the autotune directly replace the original sensor

If you just use the PCV then you will disconnect your stock O2 sensor. It isn't necessary. The AutoTune uses a wide band sensor (replacing the stock narrow band sensor.)
