EGR Delete - Will I benefit?

EGR is a crap emissions component. There are benefits to removing it, don't really care what some argue for keeping it. There is no denying fresh clean air is better then recirculated heated air. The theory it could "cool" the chamber goes against basic logic.

Remove it and have it deleted from the pcm, simple as that. Have done it myself on other vehicles and known many more who have done it with ZERO negative effects.

Big Mike you kinda sound like a conspiracy theorist. While I'm not a fan of EGR, I don't find it to be the devil. It's very simple and a smart way to do what it accomplishes. I prefer just to diable it in the tune and leave it all mechanocally hooked up. Less work and easy to enable if you need it to pass emissions.

You misunderstand the EGR's function or it has been misrepresented to you.

The EGR puts exhaust gas back into the intake stream. This isn't to burn "unburned gas" - the exhaust gas is mostly inert. The idea is that this inert gas helps cool the combustion chamber, preventing detonation (spark knock/ping.) It allows for a more aggressive timing curve on the specified grade of fuel (regular, in your truck's example.)

If you delete it, your tune will need to compensate for that in terms of the timing curve. It's something any good tuner already understands. If you delete it and don't make any change in the tune, you will have pinging, which will eventually destroy the engine. It hammers the **** out of the bearings and can damage pistons.

Basically in a nutshell you're telling him by deleting his EGR valve that he's going to destroy his motor that is the most absurd load of crap I've ever heard back your statement with facts and information.
Yes there's no real point in deleting the EGR valve unless you put on headers and usually that's the reason why but it's not going to blow your motor up or cause you to start pinging the EGR valve only comes into play at part throttle anyways. I love the internet people State opinions as if they're fact

Simply look at the inside of a intake manifold running an EGR. Wipe your finger in there. Now do the same on a manifold that's been without an EGR system.

I deleted mine on my 99' Trans Am and had a Aeroforce scan guage, no knock from EGR removal. Didn't have the codes deleted until i got the rear O2's deleted. No loss in mpg either.

To each their own, I'll stick with a clean intake and fresh air.
