Blocker Plate for the EGR
Hello Gents,
I have a 2004 6.6L LB7. 130,000miles and counting. No engine or transmission mods done. I'm looking at getting an EGR Blocker Plate and was hoping to get some advice and questions answered. Any help is greatly appreciated. #1 Does the EGR Blocker Plate throw any codes and/or the check engine light? #2 If so do I need the Finger Stick mod or will a simple tuner fix the issue? #3 If it does throw an engine code/check engine light will the truck still run normal or go into limp mode? Again any help or advice is greatly appreciated! |
Blocker plate will throw codes. EFI LIVE can shut it off without the blocker plate and it will run perfect. Blocker plate will only help when the boost hits over 20 psi and it causes the valve to kick open.

I'll be running over 20psi quite often.
Is it better to do the blocker plate or the complete delete? Sent from my iPhone using Tapatalk |
blocker plate is suitable for more boost and smog cant see it

LB7 Don't have an EGR. Duramax didn't install EGRs until 04.5 with the LLY. LB7's have no emissions

Blocker Plate for the EGR
I'm surprised how many people say that it's very interesting.
Never the less though the truck is an LB7 and it does have emissions controls including an EGR. Sent from my iPhone using Tapatalk |
Mine is a 2002 and it has an EGR. some LB7's starting in 2002 came with EGR if they were a California emissions vehicle.

Go with the blocker and finger stick if you don't wanna go to the complete delete. I ran a blocker and finger for a couple months with no issues. Have since upgraded to full delete. Also went to EFILive and highly recommend it. What a difference.

All Duramax engines are built here in the states. The factory is in Moraine, Ohio.
