Hey guys, new to this forum.

Very basic knowledge on diesel trucks as well.

So go easy on me.

Anyways I just purchased a 2008 2500 6.7L.

Guy said owner before him did the DPF delete, and tuned through EFI Live.

But doesn't have the 5 position switch.

I purchased the switch tonight.

The guy I bought it from says all he knows it is on level 5.

I don't always want to be on that.

Will the switch solve my issues?

Also is there anyway I can check what tunes are loaded?

Any info will help me!

Thanks in advanced!
