Lmm EGR delete

[Slamnek]

I've just recently had my duramax straight piped and is it worth it to get the EGR deleted? Next thing is a cold air intake.

 

[tex78]

Yes so u don't have egr and or egr cooler issues ect

I take it u have a chip to bypass the egt sensors and dpf sensor

 

[Slamnek]

Te DPF was deleted when I bought the truck and there was a tune put on it to bypass the sensor. I just took the muffler out. I've already notice a slight mileage increase.

 

[jaredszakacs]

ya youll definitely notice some good power and mileage increases. do the full delete with the the new tube but will also need a new LB7 uppipe

 

[tex78]

Yes to the lb7 up pipe


Don't just cap it off, cause it bounces around, breaks, cracks ect

Yup. Learned that the hard way lol.

You can just do a blocker plate as well and then bypass the egr with your coolant hoses if you don't need/want to fully remove it and have to buy a new delete pipe and up-pipe. Cost is only $30-$40 going this route.

U would still have to immobilize the egr valve still won't u, keep it from working

Just need to unplug and turn off the codes same as you would if you removed it.

But u need efi live ect to turn off ECM data ext for egr valve

If you go the blocker plate route you just need to buy the wiring harness kit , there really cheap and easy to instal. I believe it's " 5 finger " kit. Nadp sells them. My blocker plate and harness was less then 80 bucks for my old 07 lbz. The wiring harness takes care of computer issues

What's the difference if you unplug it and leave it in or remove it altogether? You still need to beat the codes via EFI Live, HP Tuners or a Finger Stick.

This is the easiest way if you don't have Efi LIve.

Jon's Finger stick has been around for years and works well.
Lots of people sell them.
Here are the directions on how to do everything according to Kennedy Diesel: http://www.kennedydiesel.com/docs/Finger Stick Install.pdf
As I said before the only additional thing to do would be to bypass the egr altogether with the coolant although typically they don't have many problems with leaking so you can leave it stock if you choose.

And you can still bypass the egr with the coolant hoses if you want to although the egr's generally don't have many leaks on these trucks. It's cheap and easy to do though.

I concur with lbz.... The egr and coolers aren't much of a problem for the lmm.... Why not just leave it as is?

Still can happen, coolant leak from cooler, egr valve - intake gum up issues

 

[Summitric]

Still can happen, just not as common as all the others.... And why not worry about it, if and when it happens?

 

[LBZ]

I've seen some that had no coolant leaks and were almost plugged solid with soot. It's just bad stuff and should be blocked off if possible as soon as possible IMO.

I would bypass it with the coolant lines and block it and throw in a finger stick and walk away knowing that for under 100 bucks you just made your truck more fuel efficient and run better and cooler.

But with that pic of a lmm I had apart, half plugged up is no good either


Just kibosh it and never look back at egr issues

Or just block it.
Same difference without having to buy the egr delete pipe.
