2012 Duramax DEF Delete & Exhaust

[bowhntrmatt]

To me the advantage to Chris @ Relentless is you can talk to him, tell him if you want max all out or a safe tune for heavy towing etc. He will take into account your information along with what has or has not been done to the rest of the truck and set your tune accordingly right there on his dyno. This means you get an actual dyno sheet of exactly what your gains are and that the power produced won't over stress your other stock parts.

And while his tunes make great power and mileage they don't smoke hardly at all. I'm too old to "Roll Coal"

Exactly.

My 08 cost around 900 if I remember correctly, but that was a few years back. A buddy just called them today and was quoted about 1500 for a full delete and tune on his 2012 duramax.

If you close Chris would be my choice. If you hear anything bad about him there's more to the story! Lmao many will tell you what you want to hear but he's got very good clean tunes and will tell you the risk involved as well if you wanting anything crazy. I do know he's got some killer mpg and towing tunes. But as you can tell some happy people on the green screen with his tuning!

bboswell I agree 100%

If you're handy, buy the stuff and do it yourself.

Can be done in an afternoon or a whole weekend depending on what you're doing.

I was told on your LML that you just need to unplug the egr to disable it.

If you're not going to change the downpipe, the exhaust is pretty easy. Just be sure that all the joints seal properly.

Then buy the programmer, and load the tune you want.

Yeah its really not that hard to do. I don't know why these shops charge so much. I guess its easy for me to say that about how much they charge from my laptop, but they're basically just changing the exhaust system out. Then reflashing the ecm or whatever its called. Ive jail broken things and did basic coding so I wouldn't be afraid to do that myself.
