EGR Limp mode?

[FK000@aol.com]

Is there a EGR limp mode for the 04 6.0.
If so how is it bypassed?

The only answer is the word "no"... but that's too short. Freeze plugs didn't work?

[FK000@aol.com]

Freeze plugs worked great, but now I get a EGR low flow code.
And after a hard accelleration when I take my foot off the throttle
I get an air wooshing sound from the left side. sounds like air comming back out the turbo into the K/N filter.But the boost is normal.
No grinding just sounds like air kind of wo wo wo wo wo then it stops.
Any Ideas?

I read on another site that if the EGR popped any codes it puts the truck into LIMP mode and fixes the turbo vanes to one position is that true.?

i thought the check engine light just came on, if you get a custom tuned SCT programmer they can take care of the check engine light

Only does it after a hard accel and immediatly off the throttle.
If I let of the throttle moderately or slowly it does not do it.

I wouldnt worry about it at all. I believe its considered normal operation.

Wo Ho another problem with my 6.0 ....
Drove the truck this morning and could hear a hissing got louder
when I gave it some throttle then, o crap no power still had boost but took a long time to build up. Lifted the hood could smell exhaust (great)
Did some investigating the flex tube was cracked!!
When will it stop?
