Does an EGR blocker throw any codes on the 7.5-08 LMM? I am running a straight pipe with Stealth II DPF delete. Quadzilla does not offer an EGR blocker update for the 7.5-08 LMM. Does the DPF delete suffice or do I need another tuner? Thanks!

From what I know, yes it will throw a code. You can check with Kennedy Diesel to see what is out there to get it off but the only thing I know of is EFI Live.

I had my EGR unplugged for 10K miles with a Quad S2, never a CEL. It's now blocked and codes turned off with my Edge Race Evo, lvl 4 and up disables the EGR, below that, just blocks codes. Chris

I have the Stealth II stacked with the Banks Six Gun. So I would like to do it without adding another tuner.

I assume you run the stock, no DPF tune, then added the Banks? Not sure if the stock no DPF tunes on the Quad stop the EGR codes? Might want to call them. Chris

Quadzilla tech said that the "no DPF" tune also blocks EGR codes. Thanks for the input.

Thought it did, but didn't want to tell you wrong info. I should have known it did now that I think about it. As I said earlier, I had the EGR unplugged for 10K miles and set it on stock no DPF tune several different times trying to get the best mpg tune.:cool: Chris
