CEL on EGR Delete

This has to have been answered elsewhere but I couldn't find it.

If I do an EGR delete on my '05 6.0 I know I will probably get a code. Will this do anything to how the engine runs? Will it put me in limp home mode until I get a tuner or will i just have an annoying idiot light on? My other vehicle is a Yukon with 195,000 miles on it so I'm used to driving around with message lights on.

Thanks!

Wait until your truck is cold and then unplug the EGR valve. That will answer your question.

FWIW, on my 05 the light stayed off

You should check out the Alabama Chapter of the Org. A link to the Dixie Strokers is in my signature.

Unplugging the egr valve on certain years and with certain stradegies may cause the clutch fan to not work at the proper rpm levels. Also may effect the vgt cycle mode. This is a fairly new find in the last couple of months. There is no detail on what year trucks or what stradegies are effected. Your gonna need to pay attention to your trucks behavior before and after unplugging the egr valve.

That is only on the newest strategy.

VXCF4DC is my strategy and I have no problems

Not true, I have the VXAP2N2 from 2008, even with custom tunes from ID, DJ's, and Vivians new tunes all of them were notified that I was gonna have the egr valve unplugged. With my egr valve unplugged my vgt will not cycle. If you need further proof, give me a couple of days and I can post a video.

Please don't take this personal, it's east to suggest to someone what to do to there truck without giving them all the facts. He just might unplug it and be back on here wondering why his truck over heats.

Here is a write up that a ford tech did.
side effect of disconneting egr valve - Ford Truck Enthusiasts Forums

Here is one of mine that I noticed.
Egr valve and VGT cycling experience? - TheDieselGarage.com

This is why I stated for him to pay close attention to his truck, before and after he unplugs the egr valve.

Well that's just it, members who unplug the valve don't have access to a good scanner the check there clutch fan rpm. They may be fine now, but if they have trouble with overheating issues, they may not know that unplugging the egr valve might have cause there issue. The clutch fan still works, but it doesn't work up to it's full rpm.
