Hi everyone! New to the forum here hoping to get some questions answered I can't seem to find on my own. I have a 2007 GMC 2500hd with the lbz. First off I found I can send my ecm into crank it up diesel and get a 5 way switch and it programmed for an egr delete. Has anyone sent gone through them? Also I was thinking of doing just an egr block maybe instead of delete? Any suggestions on kits to buy or should I just make the plates and stuff myself? Also is there any write ups on the delete and the block just so I have an idea on wut I'm doing before I do it.
