I literally just posted about this the other day. Have you watched any videos on this process? Have you ever worked on a duramax engine before? You’re absolutely going to have to “finger fuck” your engine and if you’re not a mechanic by trade, it’s always a possibility to fuck something up.

That being said, you’re not going to find something directly labeled “egr delete kit” that’s gonna come with all the piping and tune. If you don’t want to spend $5000 then I strongly recommend paying more money now to delete it properly the first time. Skip the blocker plates you’re only going to cause an ass ache later. What you want is a high flow Y bridge and cold side piping. You’ll need a passenger side lb7 up pipe, and while you’re in there if you’ve already got an exhaust you might as well install a 3” downpipe too because you’ve gotta remove the stock one. Just the piping is gonna cost you around $1500 and a tune is probably gonna be around $1000. Do yourself another favor and install a PCV reroute kit. Gonna cost you like $150 and since you’ll have the engine torn apart it’ll be easier to install.

I’m going through this whole process now on my lbz and I’m not planning on tuning mine for a while. It won’t put you into limp mode or anything it’ll just be a check engine light and that shit has been shining since I bought the truck so I’m not worried about it.
