Because if you don't it will through a code for the egr..... It will keep the trash from being recycled through the engine, also will help lower your boost pressure.

the stock egr unit is basically like a radiator.... coolant flows thur fins in it and exhaust gasses pass over the fins. thus causing the exhaust to be "cooled" before it enters the intake to be reburned in the cyls. the design of the EGR fins is weak and they can leak. when they leak exhaust gasses enter the coolant system and pressurize it to the point of blown head gaskets and blown oil coolers. by deleteing the EGR cooler you eliminate that risk. you need a tune to overide the computer wanting to work the EGR. since the EGR is no longer there the computer will throw a code. the tune will overide that and allow you to drive without the check engine light on

If we are talking 6.0 here, is it better to use one of the better aftermarket EGR coolers, or just delete it?

This is the 6.4 section, but I always recommend deleting (physically removing) it from a 6.0

EGR Unplugged?

What would happen if you unplugged the EGR valve if anything. This would not allow the exhaust gases to recirc through correct. Would the EGR Cooler get too hot without flow?

I have ordered my EGR delete kit for my 05. Do i have to have a tuner. I understand it will read a code and turn on the service engine soon light but will that effect the motors performance??? Or does it simply turn on the service engine soon light?
