Sounds like an awful lot of work for... some reason.

Yeah, someone is going to have to explain to me how $4500 worth of emissions control deletion is worth the money.
It sounds like it's just spite-modding with no benefits.
Nah, there's no way long haul truck owners are going to spend money just to be assholes. There's got to be profit in it somehow.
The EGR and DPF systems used in diesel trucks cause (or caused, it’s been a while since I last looked it up) a big reduction in fuel mileage. I think it was a 2 or 3 MPG reduction.Doesn’t sound like much, but it adds up when you are running 200,000+ miles a year per truck. With the system running I believe the average fuel mileage for the trucks in our company is around 6 to 8 MPG depending on the route.
Additionally the systems are expensive as all get out to repair and maintain. When the DPF and DEF systems on my truck went out, the truck was down for 3 months waiting on parts, and from what I heard from our mechanic, the final repair bill was around $15,000USD.
That said, the fines for bypassing the emission systems are big enough that it’s really not worth it, but some owner operators don’t realize it as many don’t run their trucks like the businesses they are. They just know this is expensive as hell and they can reduce the cost by bypassing them.
It's almost like we should've stuck with electric trains for long haul freight and left OTR hauling for last-mile. Almost like that would've seriously helped the CAA rather than a bunch of half-fixed like this.

Im with you. I'd love to know why.
Edit: Nvm, it's a pretty short article that doesn't say much, but it does include pictures of it.
I'm doing some reading here, too. Seems like the additional maintenance expense caused by the exhaust recirculation can be expensive over the life of the vehicle. This isn't just maintaining/reparing the EGR system, but also maintaining/replacing other engine components that have a shorter lifespan due to the emissions controls. This makes sense to me.

You will get a very large HP boost and can get better MPG as well. Also don’t have to add def fluid anymore or maintain the def system.
According to this dumbass "journalist" and his editor, this is "TuNInG"
There's a much easier and accurate way to write this article.
For semi-trucks at least, my cousin (who drives a truck) told me it costs him a lot of money to have the DEF systems on his truck and operate them, and it costs him money he would otherwise be making on his deliveries.
I thought he was an idiot, and hes risking his and everybody else's health around him with his attempts to defeat those systems. (Don't think he was ever successful at it)

It usually comes with substantially more power, and you don’t have to maintain the def system anymore either.

Money. It’s always money.
From the article:
Achtemeier charged as much at $4,500 per truck for work that often took him two hours or less. Achtemeier advertised his services on social media nationwide, doing business as Voided Warranty Tuning (VWT) or Optimized Ag. Between 2019 and 2022 his company took in more than $4.3 million in gross profits.
When you run out of DEF or the DPF is clogged, you can't run your truck for more than a brief while. You get half output in a limp-mode to go refill your DEF or have the DPF serviced. DEF is the reactant for the exhaust that makes diesel burn cleaner, but means modern trucks have 2 tanks now. Users hate it, but it cuts emissions massively. Also adds a few grand to the vehicle exhaust system in hardware and sensors and control units. Anyways:
Time = money.
For a commercial or even semi private vehicle if you bypass even one indicent of downtime by doing this is paid for itself.
That said, the DPF is a filter, and can physically clog and cause an exhaust fire if there is no monitoring software. I hope at least this guy had it wait till it was almost critical and then stop, not entirely disable the stop signal. Otherwise there is a serious risk to the vehicle and passengers.
These systems often cause issues and it may be quite expensive to repair but if you bypass it, it doesn't affect the performance of the vehicle.
Removing the pollution control equipment and disabling the software results in trucks polluting at 30 to 1,200 times the level of a truck with pollution control systems.
Fuck these people.
Reduced running costs, ease of maintenance, engine efficiency.

Trump pardons then nominates him for head of transportation
Nah, EPA.
So it's a Captain Planet villain, but dumb.
Right, a Republican, exactly.
The way they've all reacted to climate change denialism by actively trying to make pollution as bad as possible is wild. Even if the entire world's scientific community was somehow wrong about global warming, shit like this and "rolling coal" would still be terrible for air quality, but these fucknuts apparently don't care as long as they get to "own the libs". This is peak "eating a shit sandwich to force other people to smell your breath" energy.

The antipollution on a diesel engine (at least a big one) essentially reroutes the exhaust back through the engine and reburns it again. Before the antipollution devices were in place it wasn't uncommon for big diesels to get 500,000 miles before they needed to be replaced. Now with the antipollution devices they're getting somewhere in the neighborhood of 100k before they start having problems of significance.
Those engines and their maintenance are expensive as hell. It saves a whole lot more than the $4,500 having that done. It saves them hundreds of thousands of dollars over the long haul.
or they could run on propane, which doesn't make a whole lot of particulates in the first place and is cheaper anyway
I'm talking big trucks not forklifts.
out there plenty of people run their cars on LPG, most of taxis in Warsaw are hybrids running on propane because it's cheapest fuel in most efficient vehicle in urban conditions
it's pretty common in US too, just not in private vehicles https://en.m.wikipedia.org/wiki/Autogas#/media/File:2020_Global_Autogas_Consumption.svg

I’m assuming the engine would need some modification to run propane? If not to the cylinders themselves, to the fuel supply? I assume propane would be largely similar to LNG vehicles? I really only see that on city buses and assumed there was a range reason for that.
Propane is way less energy dense per volume than diesel, so it isn't feasible for long-haul trucking. CNG/LNG is more energy dense than propane, but still nowhere near that of diesel fuel, which is why you see it in busses and garbage trucks. I know a few massive fleets (UPS comes to mind) that use CNG for some of their local routes, but that is probably more for the "green" optics than anything else.

It's okay to keep the hyphen in there. It's more readable, and also it's once again a word.
Why? Just Why?
I mean sure, there is some money aspect to it, fine.
But why spend all that time and energy just to be able to pollute more. I mean, that is the benefit of more pollution? Even if you don't believe climate change, polluii less shouldn't be that hard to understand as something positive?
I'm just... Not getting this. I'm assuming the guy has a mental illness that would explain this, maybe?
Tribalism, to own the libs.
If the "delete" was removing their catalytic convertor and not just reprogramming the ECU then there is a mild to moderate performance increase caused by reducing exhaust pressure. If it's easier to push the exhaust out then there's more power going to the wheels.
If it's just ECU changes it's probably related to the air/fuel mixture it's using. Often douchebags will hack this to "roll coal" but changing this can give you increased horsepower at the expense of emissions.
As someone whose car has a tune but still passes emissions inspections, this guy is both bad at tuning cars and also an asshole.

Remotely? Sounds like the manufacturers are up to no good as well.
The summary says he was having accomplices connect a laptop to the vehicle and then remotely accessing that laptop. Sounds like regular old ssh or rdp.
I'd bet he's a TeamViewer kind of guy.
If you read the article he was remotely connecting to laptops that were plugged into the vehicles.
