delets in an emissions controlled state
I live in MA that has a strict emissions testing. I decided to do a DPF pipe delete along with EGR blocking plates. While today I simply bolted the delete pipe in and clamped it to my muffler I plan on flanging both delete pipe and DPF pipe assy back at the muffler for easy swapping. Should be an easy swap out when sticker time rolls around.
I decided to install block off plates on the EGR and kinda jacked that up. Top plate went in no issues, the bottom plate gave me problems. I ended up jacking up the gasket cause it would only separate such a small amount. screwed up the gasket stuffing something in to separate the pipes. Now it leaks a bit - need to fix that.
But I am wondering if there is a real advantage to putting plates in. I mean the EGR is shut off with the H&S tune. Easy enough to put the DPF pipe in, flash the PCM with no delete and the EGR is fine for emissions. So the question is what is the advantages of putting plates in v/s just shutting it off via the H&S tuner. I wanna keep everything intact for inspection and the plates make it a PIA.
BTW - I still cant believe the gains with these simple mods and tune. Fricking diesels rock!
