i just thought i would throw this out here for everyone. When you install this combo there is a setting that you have to enable for the autotune to do its job. You dont just plug it in and have it work. you have to go into power commander tools,go to configure and then go into the autotune feature. Once your into that you have to enable autotune,then your ready to roll. Once you turn this on you can pull your map up on the main screen and on the left of the screen you will target AFR. click that and you can set the AFR on every throttle position and RPM for the whole map
