Just bought this chip week ago from guy on here. The first setting seems stock setting. 2nd setting seems like slight bump in power idles raised up a 100-200 rpm. 3rd setting adds lots of power/very quick throttle responce but truck idles at 1000rpm. 4th had check engine, wait to start light come on for a sec or so. 5th idle raised to 1200 rpm and last seemed same as first setting.
Heres how guy posted sell:
