Fisrt off sorry because i know this noob question lol but what is a EGR Delete how do you do it and what does it do when you delete it??
 


Disconnect the electrical connector ontop of the EGR, unbolt the EGR from the engine, and block off the 2 inlet ports (one on the lower intake manifold, and one on the read exhaust manifold).

It will keep your intake manifold cleaner (no recycled exhaust gases), and your temperatures a little lower. You may notice a slight drop in fuel mileage though (some people do, some don't). I like it mainly because it cleans up my engine bay, and my EGR was leaking, and annoyed the hell out of me.
 
I pulled the hoses and RTV'd pennies over the hole in the lim and the hole in my rear header.

There is no power to be gained from deleting the EGR as far as I know, but you will have a cleaner motor because it won't pull in exhaust anymore.

Also, you will need a tuner or a PCM with the EGR codes deleted or your CEL will come on and stay on.
 
just to clarify, deleting the egr RAISES egt's. The egr is used to cool off combustion temps by recirculating exhaust gases through the intake. It's taking the place of fresh air fuel charge. The already burnt exhaust is cooler than a fresh/ new explosion. This is why the PCM commands more timing with egr on, to increase lost cylinder pressure (lost through the decrease in torque from the deluted a/f charge) and the cooler temps allow more ignition lead.
