It sounds like I am going to be ok without the EGR as long as I have everything properly set up. I am having my computer flashed soon and needed to decide whether I was going to have the EGR enabled, or not.

I have a 2003 5.7 Hemi block with stock replacement pistons (.030" overbore) and a new Mopar stock camshaft for the 1500/2500 series trucks. I am going to run a 192 degree thermostat. I am going to only use 89 octane gasoline as well. Hopefully all that and a good cooling system will keep my engine running properly...
