08 LMM EGR AND DPF DELETE
 

I bought a 08 LMM Duramax a little while back that already has a DPF delete, and I assume to have a EFI live tune to tune out the DPF. Well now I'm pretty sure my EGR cooler is leaking. I want to do a EGR delete using a H&S mini max. Do I need to somehow remove the EFI live tune before I install the H&S tuner or will the tuner do it for me?

Should work just fine. No need to remove the efi live.

Can't the EFI be used to delete the EGR?

Yes but I don't have the autocal used so I don't even know if it was EFI live or not

Ok I got with the former owner and when they did the DPF delete they used an edge cts 19311, and just left it on a base power tune and kept it. Is that the same as an edge cts race? And which is better that edge or a h&s mini max. Also will that edge delete the egr? Also will that edge tune be locked into the ecu?

Ok how do I set this edge cts race to do egr delete? Also which is better the edge or the mini maxx I was thinking about just using he mini maxx because it tunes on the fly.

So I'm looking into buying a newer truck the only reason is because my LBZ was totaled two weeks ago. I am super bummed out because it was my first diesel and I want to go bk to LBZ but I do want something newer. I was looking into an 08 but I've been seeing how the LMM have the Dpf. Haven't really looking into 2013s but I want to know what people think on the LMMs
