There is so much dumbfuckery in this thread that there is no way to respond to it all. The fact is that DEF is so effective at reducing NOx that it allows fuel injection timing that we used back in the late 80's. Very fuel efficient timing, and yet we have NOx emissions that are 40x less (8 vs .2 grams per horsepower hour). And yes, even though some of these agencies are dumber than this thread, they can estimate the weight of that shit. DEF (urea) is not some "kickback" scheme, it is used for a chemical reaction that converts the NOx to Nitrogen and water. We are getting power out of stock 6 liter diesels these days that we used to get out of 15 liter engines just 30 years ago with no emission controls. Many Class 8 rigs are getting over 7 MPG now and we begged for 5 back then. That's all real life numbers. I literally test HD trucks for fuel efficiency for a living. All with modern emission controls.

With that noted, I am not endorsing all emission laws or the idiots that write them, but I can guarantee you SoCal has benefited from PM and NOx reductions. Counting CO2 is the biggest scam in history, but actual pollutant reductions are a good thing.
Some people are leery of technology. They don’t believe or trust it. Doesn’t mean they are correct but there is no way to convince them otherwise.

I know people who still insist on carburetors over injection. They insist it makes more power. Fortunately they have moved past points and a condenser. 🤷🤷🤷🤷

Good point. I read this from the perspective of a 40 year diesel career. My biggest issue, as noted in a few posts, is that emission deletes HURT the diesel industry. Regulators, and the public, will simply demand outright bans if their perception is that diesels blow black smoke. Probably inevitable considering they believe CO2 is killing them, but these are amazing machines and I like them...

In CA, it's been illegal to mess with any factory emissions system since 1974!!!

🤣

All these guys doing "tunes" have been knowinging doing this in full violation of the law since day one.

It was just a matter of time.

With that being said...

They will have to pry my Superchips Tuner from my cold dead hands. 😁
In California it’s been illegal to mess with factory emissions since 1966. In the rest of the country messing with factory emissions has been a violation of federal law since 1968. It has generally been cited as a correctable offense. The feds have never gone after individuals for tampering, leaving it up to states to enact their own statutes. States without “Non Attainment” areas never had to enact such statutes many other states have but don’t enforce them. Even in California it’s rare to have a tampering violation unless they are targeting street racers.

Can't convince me that making trucks run DEF with the added packaging, manufacturing and waste (plastic containers) that goes with it is better for the environment. Someone is getting a kick back somewhere.
add in the huge impact of decreased mpg due to the emissions crap along with the increase in service needed as well.

Selective Catalytic Reduction (SCR), which requires DEF, IMPROVES fuel efficiency dramatically. Service work is a valid concern. Hardware additions and the impact on landfills, OK, maybe a slight increase. We're talking whole trucks here and the percent increase of stuff. Pretty small percentage.

BTW, I hated the idea of SCR when first proposed 30+ years ago. I'd have bet my house we wouldn't have adopted it as widely as we have. I was wrong on both counts. SCR is kinda magic.

I have zero sympathy for folks who think “rolling coal” is cool…what the fuck did you think was gonna happen?

Imbeciles.

Better to stay under the radar, especially if flaunting federal law.

Rolling coal is about is smart as driving with your hand out the window with beer in it.

Well sorta...

Any vehicle, 74 and older does Not have to be smog checked. So if no one is checking, you can do whatever you want!

But there is a cabal that is responsible for concealing the technological breakthrough which produced a carburetor that increases gas mileage to 100 MPG. It was discovered in the 1960s, but suppression of that fact by the oil companies, automakers, and politicians has kept the public from realizing its benefits.

Rolling coal is the equivalent of driving a wake boat full of ballast with no rider.

Edit. I exclude diesel competitions where the motors are making 2,000+ HP and have no other option to make that kind of power.

I have a PPEI tube in my truck and it’s by far the cleanest tune I’ve ever had in all my trucks. He has ways to make coal rollers, but he’s also the baddest sob in the business when it comes to the Duramax tunes. Sad to see that this has happened to him.

Not that I know anything at all about that market or world, but "rolling coal" just seems like a reason to be lit up. It's a way to draw unwanted attention to any modification.

You should be lit up for "rolling coal" it's a huge safety issue. It's also a sign of a junk tune or tunes. I don't know why any tuners write these in for clients as it draws attention to themselves as well.

I am that jack ass that bought a 6.0 in ‘05. I put the complete banks kit on it at 20k miles. I lifted the heads off at 22k miles pulling chirracco. Never tuned another motor after that. I wanted to, but my old lady never forgets that price tag. And reminds me every time I want to do anything like that.

Mine is getting done this week. In Alabama the resale value of the truck goes up when its been deleted. I am not asking any questions, local shop owner does it but he does it at home, no ties to the shop, all cash.
What year was your new one again? If it’s a 19/20 and the pump swap hasn’t been done wait…dealer won’t do it if deleted

Sorry to hear about your misfortunes. A good tuner also knows the limits of the engine he tunes.

Raceme is out of Austria and has yet to have an engine or drive line failure traced back to his tunes. (I may eat my words years ago when I was helping a friend with this process "he had yet to have an issue") He has a lot of respect from respected tuners here in the U.S.
He also provides a tune that is 100% stock hp and torque.

I don't speak for your experience but although the high performance settings or tunes are fun they are what get you into trouble. Also I've heard if you're towing a tow tune is a must.

Too bad the government doesn’t put as much effort into finding and prosecuting people who steal elderly people‘s life savings as they do looking for a few smog violators. 😡
Right.... Flat out pathetic

If my 11 Duramax didn’t have issues with the DEF sensors, putting my truck in limp mode when I still have over ¾ of a full tank of DEF, and crappy fuel mileage from the DPF triggering a regen every 200 miles, how it never limped to or from the river I’ll never know, but deleting it made it reliable and bumped up the fuel mileage considerably.

A puff of smoke works great to clear the asshole that doesn't comprehend why there is a flashing light on the truck and trailer...

All I will say is, they read forums too. Some of the governments evidence against Kory was pulled directly from the duramax forum. I've never heard of Kory writing dirty tunes. Always heard great things.

He also posted on Instagram they were doing this. The bigger question i have wondered......how much about Korys clients do they know?

Diesel emission rules are rules I agree with . The diesel industry is going through teething pains just like gas did . Gas engines run great with current emissions controls . I HATE getting behind ANY deleted vehicle , pickups , 18 wheelers , buses etc . Plus the asshats that like to roll coal at people .
I hope your transom never has any soot on it

I also bought a 6.0 in 2005. My wife looks at me sideways whenever I look at a Ford after that ass-raping experience with the 6.0. The shame is the rest of the truck was amazing.

Probably have one of the last 03 F250 7.3 Lariat's with under 125k miles. No DEF No CAT.
I have one that just rolled 100k miles on the last river trip and is in pristine condition. Will not be getting rid of it! I bought it from the original owner a few months ago, funny thing is he offered me $3k more than I paid him for it the day after I wrote him a check because he realized he fucked up getting rid of it. He was not happy when I said no.

From what I learned being in the trucking industry those were the blunder years of modern emissions on diesels. Even class 8 tractors fell victim to all the new laws and engineering mistakes. I agree you probably could not fix your truck without deleting stuff and needing some kind of "tune". I mean, can you imagine trying to fit all the newly engineered stuff onto it? Nothing would fit, it would be a nightmare and $$$$. Apparently now things are engineered a bit better and we are just past those blunder years. It will never be as reliable as a dead simple old school (like pre 2000's?) diesel or marine/industrial (emissions exempt) with zero emissions controls on it, but whatever.

The funny thing is you can sell 100 funds of fentanyl enough to kill thousand and be let out on own recognizance. But don't you dare mess with computer system on new cars. What is wrong with the government

It’s pretty amazing actually, I remember going to a truck pull as a kid and getting sick from all of the smoke from the “coal rolling” semis during the semi pulls. And now, my Ram has 900ft-lb stock with no fumes or smoke.

Just finished a 5000 mile road trip- and was amazed at how many hot shotters were deleted, I saw many of them blowing a cloud of soot on the grades throughout the western states.

When you make a living by the mile the last thing you want is to be in the shop constantly due to emission issues. I can see why they delete their stuff…

The .gov forced all this on manufacturers long ago and they are just now “starting” to get shit figured out. Life was so much easier in the old 12 valve Cummins era when shit would run forever and be as reliable as a good dog.

I get it. Just figured they would have cleaner tunes or be worried about gettting rolled by a state with emissions requirements.

“Cleaner tunes” and Electric cars disposing thousands of dead battery cells into the ground, funny how everyone is so worried about it all of a sudden yet we’re the only country weakening ourselves over it. This country needs to grow a pair again. China is laughing at us!
