I completely agree with you, a custom tune is probably one of the best things that you can do to your truck. Now time for the free advertising again for Allen, the Nelson tune is AMAZING!

I just asked this question a few weeks ago. Some of the responses I got were that even with a custom tune, it canges other things and still runs like crap. Now if anyone has actually done it and gotten good results, post up. I know (have heard) that you can't just toggle them off with a tune without changing other things in the tune to make up for it.

Believe it or not, EGR actually decreases cylinder temps and helps to eliminate pinging (one of the by-products of it's design as an emission device). As hot as that exhaust is, it's still cooler than what's going on inside the cylinder. Now, if the engine starts to ping, and the PCM pulls timing, egr deletion just created a loss of power. The pinging alone is wasting power even before the PCM attempts to correct it.
If KR isn't an issue, and the cyl temps are cool enough, then egr will really do very little for you except to save 1/100000000000000000 of the atmosphere, and create carbon build up in places you don't want it.
