H&S mini maxx

[Fishinag22]

Thought I would put this out there. I have a H&S mini maxx for a 2011 Duramax. Do any TBH-ers out there know where or who I can contact for an update to the tuner? I would like to have an update, if possible for a full delete, to have a 'clean' tune that does not blow black smoke.

This might be a long shot but I thought I would ask.

Might be peeing in the wind. I have heard a lot of guys are having the same issues. You might be better off calling a shop that sold the tuners and see what they recommend.

Interested in results.

My understanding was H&S tune is pretty much a set tune with 4 different power levels. When I got mine, it was H&S, with it's preset tunes, and EFI Live if you wanted to customize tunes, including fixing the black smoke.

Now that H&S is out of business, I doubt there is much development/updates available. Here is the manual:

I’m pretty sure H&S isn’t closed but they are no longer supporting or selling the mini Maxx stuff is my understanding.

Just install it and delete.....your right foot controls the smoke.

You are correct, my bad.

It looks like they are completely out of the tuner business, but they still have tons of high performance diesel stuff on their site.
