I have been told from 2 sources that the Diablo for the LBZ will NOT block egr codes like it does for the lly engine. I emailed diablo on the issue but no reply yet.

I do plan on putting the blocker plate in mine asap. Right now the Finger stick is the only way to stop the codes, but some owners still get codes immediatly, some weeks later. For me the thought cutting wires on a brand new $40K truck/computer causes heartburn. I may just install the blocker plate and let it drop the egr codes until a programmer is made to stop it.
