Just a thought. any fueler/tuner that eliminates the O2 sensors does not allow those said sensors from giving up to date actually readings. so those tuners will not be found on my ride
I would tend to agree with you Canuck, I had a PCV on my 2009 SG and I never realized the O2 sensors were disabled with that setup.
Initially I had them plugged in thinking they were actually doing something then someone mentioned they are not doing anything anyway. I disconnected them and no change in the performance.
I did have the bike dyno'd and proven it was safe, however it bothered me knowing that if something were to change the power commander wasn't going to do anything to try and correct a lean or rich issue.
