I installed a tuner on my LMM. Ran it for about 30 mins driving around etc. It died on me now it runs for a bit and shuts off. Does this have something to do with the DPF in the exhaust? If so how do I clean it?? Thanks guys

We need to know what kind of tuner you installed and what all is done to your truck. Look in the user CP and fill out your signature. it is a breif description of your truck. It really helps answer some of the preliminary questions

I ran the XRT from hs performance. I'm an idiot and need to learn what it screwed up. no mods except for a drop in K&N.

Well there is the problem then. Dump the DPF and then see what happens. Is it throwing any codes or a check engine light??

Duramax Power Levels: Stock, 60hp, 120hp, 180hp

i loaded the mild tune which is 60hp.
I was instructed to 'reset the transmission' on hot so i did that, then loaded the mild tune again. Ya'll guys are so helpful, i really appreciate it! i am quickly learning that its this darn DPF in the exhaust.

Disconnect your batteries for a couple minutes and unbolt the DPF at the flange in front of it. You can run the truck with the exhaust there it will just be a little loud in the cab until you get a delete pipe or whole exhaust.
