EGR Delete side effects?

[travsav]

Just got my '07 F350 back from having my EGR deleted (the cooler had clogged)...

#1 - Check Engine light came on on the way home
#2 - Heard the fan clutch (or clutch fan?) kick on after i drove it for while (only happened the one time so far)

Fuel MPG has been decent 17.5-18mpg... vs 14mpg i was getting prior (however it was cooler here in the middle of May, little more idling)...

Anyone else have any side effects they've seen? or any tips/recommendations to avoid some?

Thanks,
Travis

Your EGR cooler was clogged?????? Either way, yes, you need to have a tune built that has your EGR system as not there. Otherwise you will get an insufficent flow code.

So, you are saying that they replaced the oil cooler at the same time?

If you don't have gauges, you need to get some.

Scangauge II $160 (this doesn't have a way to see EGT or Fuel pressure)

Edge Insight $380 or so, more with probes for EGT and fuel pressure.

I did notice my MPG's go up a bit also. I have a 06, I still need to delete the code yet (need SCT) I just take my diagnostic scan gauge along and delete it when its warmed up. It dont come on again till the truck cools.

I didn't notice a difference in mpg. Which Is fine with me. But the truck runs a lot better with the delete. It will take slightly longer to warm up though. Not enough to worry about. Egr delete= one of my best mods so far!

I didn't see anything about him replacing the oil cooler but I hope he did. If not he most probably needs to.

I agree 100% on the gauges. That's the first mod that should be done with a 6.0.

SCT Livewire will let you tune and give you the guages

The Livewire won't do nearly as much as the ScangaugeII or Edge Insight CS/CTS.

From what i gather certain trucks will throw the CEL after an EGR delete and some will only throw codes.
My 04 does throw a code and my boost pressure seems to have gone down by about 5 psi after the delete
Some other guys have even mentioned that the cooling fan doesn't cycle as often after the EGR so i think im going to plug the valve back in and see what happens
