I have an 06 model. Talked to my mechanic today about this exact issue in this thread, eliminating the EGR valve. He was telling me that there was no way that he knew of to eliminate the EGR valve without the computer knowing and going into limp mode. If you blocked off the intake to the EGR the computer would wonder why the EGR wasn't getting hot and why the air flow wasn't showing any change in the air flow sensor and go into limp mode, etc. In other words each system checks and balances itself. Tell me what is the "proper way" or "the correct number and order of steps" to go about eliminating this from the system and keeping the computer in the dark so it doesn't go into limp mode. Even the ford mechanic says it ( the EGR valve) is a piece of junk he doesn't like but we have to meet regulations. Any other info you need on my truck for a response?

but yes, you could get an SCT from matt and have him program it for better shifting, no egr, and better economy without ever adding enough HP to hurt your motor... keep in mind that even stock vehicles have issues

he took a freeze plug and modified it to fit better (smacked it with a hammer) and it was a perfect fit. not sure of size you'd have to ask him.

you can simply unplug yours with no worries about a CEL unless you have a california model. you have to ask matt about the size, as it was kinda complicated.

oh ok sweet thanks i wasn't sure on my yr model and i'll talk to him bout the plug... sometimes modifying ( using a hammer) is the best route to go haha thanks

I have gone and bought myself a block off plate that is supposed to slip in between the uppie and the EGR. I'll be doing that sometime soon, I hope. Anyway, when you did block the flow to the EGR, didn't the computer throw a CEL at you? When I unplugged mine it did, got wiser and pluged it back in. Just don't want to go throught the trouble of blocking the ******* off only to have another CEL.

you must have a 50state model, in which case you have to leave it plugged in. but being an 04, you should still be able to block it off, since i think you don't have "egr flow" sensors like the 05

Let me confirm, unplugging the EGR will not prevent exhaust gasses from damaging the cooler but, this is still even the risk you take by leaving it plugged in. A block off plate would completely eliminate the issue altogether.
Is this an accurate statement?
Also, I'f I pickup the EGR block-off plate, what is done about the EGR valve? Is it just left in the closed position unplugged?
Thanks
