Egr off tunes without delete

[cooper09250]

Hello
Can I run Egr off on my Spartan with the Egr installed. Im looking to maximize life and mpg. Any suggestions. I already have dpf/cat delete and afe intake.
Thanks

Yes. However, it will cause your EGR valve to clog overtime and become stuck shut. If that doesn't concern you or you plan to eventually delete the EGR anyway, go for it.

Can you remove the EGR valve, install a block "spool" in its place and run the truck as is without turning the EGR system off with a tuner? Pretty much the opposite of his question. In other words, do the delete without turning it off. I ask because I have done this a month ago. Yes, my check engine is on. That doesn't bother me. What i'm concerned with is my system sensing no flow and telling my turbo to do certain things. I also have the muffler and cat conv. removed.

Thanks for the input. Are there tunes that just cycle the Egr at idle and what are the safest for dd and towing less than 5k. Thanks

Put blocker plates in place to prevent the EGR getting clogged over time.

You can't on my year model because there's a lip on the up pipe that inserts into the egr cooler. Male and female type piece. If I slide a plate between the 2 on the back of the cooler I won't be able to butt them back up to where the clamp will go around it. As for the egr valve...it's zip tied to the engine right now because I have a blocker plug where it goes.

Does anyone know on 6.4s are the block off plates as effective as the egr delete

Where do you live? Remember, in smog states, your gunna haves issues every couple years..... The EGR is usually the first this they look at in the test.

LDH go over to the 6.0 section and we can help you out over there!

Not as effective since you will still have coolant running through them. However, the coolant is no longer being heated by the exhaust and can no longer get into the engine via the exhaust and intake manifolds.

But, they are the next best thing and usually the only option if you live in an emissions state.
