I disconnected my EGR and my bone stock truck runs great. I will be going on a 7,000 mile trip VERY SOON, will I hurt anything leaving the EGR unhooked???????

Sorry for beating a dead horse

Come On Guys, What Do You Think????

Short answer, it should be fine. Read through all the other EGR threads and you'll find all the details.

Several HUGE threads on the topic. Sorry to say, you will have to read and make up your own mind.

You may hurt the egr's feelings. :D
Seriously though. This is a matter of opinion. You could set off some code. Just make sure the thing is in closed position. There are some blocker plates available on this forum.. Do a search.

I've had mixed feelings on this. Hard to pin down, but it sometimes seems to run better hooked up. Planning to try one of Fingers' gizmos and see what that does.

There WILL be fault codes set by simply unplugging it, just no SES light on the "Federal" emissions trucks...

I beg to differ on that no ses light, john...I unplugged mine in september, and after running for about 15 minutes the light came on....(regular fed emissions truck)

thanks to all who replied, HAPPY NEW YEAR!!!!!

the SES light will in fact come on but only after a certain amount of EGR codes are written to the ECU- not sure what the limit is. You may not have the SES light on, but have codes.

Vary the resistance and try to keep the speed the same. Then we could look at things like economy, response, temps..........

Personally, I don't run at WOT much. Well, not that much. ):h

What is WOT?

watch out timmmmmmmmmmber. or is it wide open throoooootle.

I would like to hear more from the people who tried this back in Aug of 2004 . This is when Max Power first started the idea. Are these guys still happy, or did they rehook the EGR. I read where some thought it did not work. Claimed fuel milage went up initially, then went down. Truck ran poor ect. We should have had some good feed back by now. What's the saying, COME ON GUYS! Or maybe no one has the balls to admit it does'nt work. Cause if it did, I think you would see more pos. inputs. Don't want to put Fingers and Robby out of business. They have done some super things to help us all. We owe it to them to give them some feed back, pos. or neg . Just my 2 cents . Rick

I agree with you Brutis. I have bought the plate and stick from Robby and Fingers and I appreciate all their work. I have yet to install them though. What are your observations guys? Can you honestly tell any difference in mpg after an extended period of time? Or do you all believe that the main benefit is keeping the oil and engine cleaner?

I have been trying to figure out how to tune up my truck to be more like the LB7 (quick rise in torque, flat peak torque curve). Some info I read on here makes no sense. When I unplugged my Egr (to get some low end torque), my truck sounded like it spooled a little quicker initially but felt like the tranny was slipping (no better from the light, less torque?). Shortly after (within a day) the difference was not noticed. I left it unplugged for two weeks (I have a very regular driving week in the summer, a commute between two cities and similar daily driving schedule, same refueling days, approximately 900km, been the same for about six years), and I lost fuel mileage and power (specifically highway passing power). Plugged it back in on the second weekend and immediately noticed better from the light accelleration. First highway spurt, I had black smoke. Within a week, my passing power returned and in the second week of being plugged back in my mileage had returned to previous #'s. I redid this test for my self (because an Egr and a cat on a turbo diesel can only lead to future problems, soot in oil and soot plugged cat) and the same results occured. I also tried the unplug thing to see if it got rid of the low speed surge. within a day it was more pronounced (the surge). Fingers, this is why I keep asking for input on your stick, I want it to work. If it does not change the way the computor manages the engine then on my truck it will lead to problems. I think, from my testing, that with the EGR unplugged the initial throttle over fuels then middle positions provide less power (could be less fuel but more likely less boost). IMHO, the EGR unplugged, leads to a plugged cat (if so equipped) and less highway passing power (roll on passing), if no other changes are made. It also makes the truck feel peakier (no power till you WOT it). So, does any one out there, have a combo that runs good with the EGR and cat removed (feels like a LB7 with 20% more). By the way, the 6.0 Fords this winter (EGR unplugged, lots of cold warm ups) are plugging the cats very quickly. Some are splitting the cat housing, some are blowing chunks of the cat material out internally on relatively new trucks. Thanx Geo.

I blocked the EGR to reduce the heat load. I came up with the Stick to stop the codes from blocking the EGR. I personally have not seen any great performance/economy gains, but the heat loading is down, so the EGR stays blocked. My driving/towing habit varies too much though to have anything stand out long term. If it is keeping the engine cleaner, well, that is a bonus. I never ran for any extended time with the EGR just unplugged. I am sure i am not losing anything with the plate/stick combo.

BTW, early on, I was switching back and forth a lot and managed a couple times to not get the plate prototypes installed correctly. (leaked) I knew it because my milage would dive 20%-30% but the truck seemed to run fine. :confused:

fingers, would a change to a cooler thermostat take care of the additional heat generated by the egr system ? i know the soot issue would still be there thanks

I disconnected mine back in August and only hooked it back up when going to dealer for service items or TSB fixes. I have no regrets. I think the mileage is a little better but not a whole lot. Turbo response is better and no crud going back into the engine is a plus in my book. Now I have the blocker plate and fingers stick. No more codes or CEL. I also removed the cat. No more hairballs.

No, the problem appears to be heat rejection capacity of the cooling system. There is a HUGE thread beating this topic to death.

I also unplugged my EGR back in Aug. It definitly seemed more responsive and a little better mileage at first. But after a while it seemed to go back to "normal". I now have a Hypertech & a blocker plate, but have yet to try them together. Since winter was setting in, I figured I could use the extra engine heat produced by the EGR.
