I recently purchased a 2011 Cummins that had a H&S Mini Maxx tuner installed with Sinister diesel hardware.
The other day the Mini Maxx reset itself and now my performance is saying stock, before it said performance for the level and the bars were all the way up.
I need help trying to figure out how to get it set back to performance level to get my power and settings back right now it feels stock and not like it did when I bought it.
Thanks
