6.7L Cummins Forum

I have heard about people unpluging the egr valve to gain mpg so i tried this on my truck. It whent from 14 mpg to 19 What i was wondering is if i could plug the egr valve back in to clear the cel and put a block off plate in the egr cross tube any thought s ? thanks

I know it's been a while since you posted, so I hope you get this.

When you unplug the EGR, you will get a code until the end of time unless you have some way of clearing the code (read: fool the computer). This is done with a tuner. Many people use Smarty and I have heard lots of good things about them. I have one of H&S's tuners and am very happy with it. You can pick up a good EGR delete kit for around 100 bucks and put it on yourself. BUT.... I would not recommend plugging the wire back into the EGR and then trying to block off the tube. When the EGR "gate" is opened, it is trying to send exhaust gas back into the intake to be recycled. If you leave the EGR plugged in, then the EGR continues to let the gas pass thru the tube, but your plug won't let it. This will tell the computer that the EGR is stopped up and needs cleaning, which throws a code of it's own.

Will blocking off the EGR decrease soot build up in the DPF by allowing exhaust to burn hotter?

How are you able to get 14 mpg (in the city?)? Please tell a little about your truck please. I started off w/ 10 mpg (EGR plugged) to 13 mpg w/ it unplugged.

I have had my truck for about four months i bought it to tow my camper but i havent whent yet. I am in the hvac field and have a company van i drive so i only drive the truck about 6 miles a day in town thats how i figured my milage . My truck is completly stock and has 190k on it . Sorry about the reply it got hot so i am working alot of hours.

Hi im new here an i have an egr/ dpf delete question i recently changed my ccv an oil right before like a day before i changed the ccv filter i got the check engine light pulled the code came back something bout turbo positioning sensor blah blah after looking it up ...figuring i got a dirty turbo now i know turbo gets like that from ccv being plugged i also know the turbo has been flushed before but i wanna pull it an clean it myself feel i could do better then a dealer flush...any one know a good tut on this ? but my truck has 107xxx miles on it im sick of the egr an dpf emissions bs wheres a good place to start on this an ? but as for your milage im gettin 15-16.5 in town ...an an 17.2 - 18.5 on the highway all stock 17.2 comes in at 73 mph

diamond eye makes a good dpf delete it's what i have on my truck. to delete the egr you will need a programmer to reprogram the truck. I went with the egr/cooler delete from H&S and have a black maxx tuner as well. the truck runs amazingly well with all that emissions stuff removed.
