Just found out I can't run autotune without O2 sensors. This really disappointed me. I have to find a canned tune when I put my Cams in or get an updated exhaust and updated kit for the power vision. If I knew this I think I would have kept the stock exhaust and aircleaner. I have to learn how to use the software and I doesn't seem to be as user friendly as I thought. This is just first impression so If anyone has any tips feel free to chime in.
