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?!?!?

It says it's not shift on the fly for lmls if that makes a difference.

Can always solve it by getting EFI!

Well then, can't complain about that. But I wouldn't ever pay what they're asking for them retail.

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

Have you got this figured out?

Are you tapped into a key on fuse? The truck has to be off, and key turned to the run position but not running when you start the process.

You could also hit the switch on the side that will just run off battery.

Welcome by the way.

I believe they are selling tuners out if Canada but are no longer giving tech support . You can still get unlock codes and MCC stuff.

Do any of your Buddy's have trucks you can test it on? Just to see if its the tuner. Personally I would sell it and get efi. Minis go for 1300ish still.
