I recently picked up an 09 that the last owner deleted with a Mini Maxx already installed. Everything is stock on the truck but the deletes and mini maxx.

I got the DPF FULL message so I reloaded the tune and was unsure what options to select. I also noticed that it says "High Sulfur Tune" for the tune file...

Can anyone help give me any direction on this?

Should I leave the stock parameters on everything? Should I change anything?
What's the deal with the High Sulfur Tune?


Thanks for any help you guys can offer.

 

I would call H&S performance and ask them,I'm getting ready to put their mini maxx in my 2008 ram and seen the high sulfer setting but I know as much as you!
