Returned it back to stock and now...

Has anyone turned their tuned and deleted 6.7 completely back to stock? I just did today because I couldn't make myself fall in love with the tune. It's a SO much smoother truck stock. Now I'm getting a CEL. It says EGR control valve stuck open. I'm just wondering if anyone else has had this problem after returning to stock.

What tune did you have If it was the h&s I felt the same way until I updated it friday. Now its alot smoother and dosent lug when just crusing. The tune I had was .17 now its .19 hope this helps.

It was a mini maxx. I didn't try the new update. I'm just gonna try it stock again for awhile.

Someone else on this forum had their truck tuned, and returned it to stock, and had the same issue if I recall correctly... They took their truck in and had to have their EGR replaced by ford, and I think it was all taken care of under warranty.
The EGR on a 6.7 does not cycle through like on a 6.4, so you typically get alot of soot build up on it.

I noticed how hard it shifted and how fast it would go through the gears wich would make it lug when not puting your foot into it. I had just installed mine 2 weeks ago and I was ready to go back to stock. I decided to call H&S and let them know I was unhappy with there tune they said they where working on a new overdrive tune and that it would clean all of that jumpy sh-t up. It did I downloaded friday and I am very pleased with the programer now. everthing seems to be runing and working great.

I might have to try it with dpf on. I'm going to get this EGR problem taken care of first. I guess it will have to go to Ford tomorrow.

Did you unplug the 2 egr valves under the hood when u had the truck tuned?

I just had my egr deleted, it was exceptionally clean even with the high miles. I inspected it and was impressed!! I was told it is not positioned the same as the 6.4, my ignorance as to what the difference is...however it is clean!! Surprisingly.
