If you have an SCT for the 05+ trucks, you can eve get a stock tune with the EGR function turned off. I think the X-cal 3's even have an option to turn it on our off right in the menu maybe?

I have a o3 f550 and what i did was replace the egr with a solid spool that i bought on e bay, i then bought a egr delete kit and just replaced the up pipe, i left the egr in place with the exaust opening open. I figure if its going to leak it will just leak out the opening and and no harm done. It seems to be running a bit cooler too
