When I get a tune I'll have the EGR turned off but I'm not getting one just to turn off the EGR. ~$300-$400 vs Free, I think I'll keep my vaccuum hoses re-routed until I'm ready to get a tune for performance as well as EGR delete. I removed all the tubing like you did but I left the EGR valve connected to the tube, just remove the 2 screws and the exhaust flare nut. I removed the fitting from the exhaust and used a plug instead of a cap, it leaves less stuff sticking out from my header. The Focushacks workaround explains the vaccuum hose routing pretty well. I've had it done for 4 years and never a CEL for it.
I did it for purely looks reasons, I've noticed no power gains nor higher fuel consumption.
