    I went to the menu, then install download. When I turn my key to the off position the screen turns off instead of taking me to the next steps, and there isn't any options for power level change. Thanks for the reply guys Sent from my iPhone using Tapatalk

    Power levels on mini maxx

    I have a 2012 duramax lml. Tried to change my power level on my mini maxx. I couldn't find the option on my mini maxx, called h&s and the guy said it's a fuse. I couldn't find a bad fuse. Can anyone shed some light on what else could possibly cause this?!?!? Sent from my iPhone using Tapatalk
