Question about stock running boards

[Jhernandez909]

also if you live in a state like California where they smog how is it possible to delete the def and so on? And wouldn't that mess with your warranty?

I met a guy a couple months ago that did his. Def gone. Egr had two blocker plates. He said he had close to 1200 lb-ft torque tune as well.

Funny that no one on 2 very busy duramax forums know about anyone that can delete am L5P..;..

 

Now it's an LML (2011- 2016), then that's a different story. Lots of deleted LML's out there.
