My 2013 5.3L has it. I'm sure it continually varies. New tech comes along to help improve emissions and fuel economy, thus maybe allowing it to be eliminated. But then new emission or fuel economy requirements move the bar again, and then it's necessary to press it back in service. Kind of like A.I.R. pumps going in and out of use the last 5 decades.

@68Formula Not calling you a liar but I have never seen a Gen IV truck engine with EGR, pics or it didn't happen. EGR quit on trucks in 02 maybe early 03. I do see on RA that you can buy an EGR gasket but I guess they are not making EGR valves? My in-law's 2013 Suburban does not have EGR. All GMT-900s I've ever worked on do not have EGR.
@njm12333 You talk like a bot or an EPA agent. I would watch out for this guy...

You must be a conspiracy guy to think some stupid **** like that honestly. You really think anyone cares about what guys do with their cars? Outside of California I should say. Not to mention egr systems are not required by any law.

EGR... exhaust gas recirculation system
Emissions part, and "could" cause you to fail testing IF they test in your area (not all do)
I doubt you'll see any difference in MPG or performance, but it's potential to foul intakes/throttle bodies/plugs is real.

Funny, thought it did and lazy looked up on RA too. Like you said it showed the gasket, so I ran with it. Actually went out after work and peeked under the hood, sure enough nothing. WTH RA?! At least now I know why my gas mileage sucks.

Yeah, I think EGR (at least in this generation) was due to emissions. I think it had to do with the ECU and the camshaft. I also concur they deal away with in like 2003-ish (not sure if that coinsided with the P59 ECU or what? IDK) and not aware of EGR in Gen IV vehicles.
I'm not sure there's any power gains by removing it, in of itself, again, because it's an emissions thing. But I've heard this other forums (probably by folks that don't even understand what the system is or does.) Delete it to keep the intake cleaner, sure, I vote for that.

Actually I do. The EPA has used forums in the past to go after shops and people who remove emissions systems from their cars. So yeah, I am pretty sure people care. Not even a conspiracy just a fact.
