Being able to think critically for 7 seconds doesn’t make one a bot. There’s a ridiculous amount of misinformation going around (primarily spread by 1 person on social media dressed like a smelly cab driver) about emissions regulations and my point is to address it.

It's not going anywhere. Y'all should know by now the "show" is always better than the reality. Reality is de-rates are still on the menu, only now the time period before a nearly full de-rate you get is a bit longer. Couple this with massively increased warranty requirements for aftertreatment...

No reputable tuner is going to touch deletes. Not sure why y’all are still getting your info from sketchy social media sources when you can just read the EPA proposals yourself. Automotive emissions are governed through the Clean Air Act. Being an Act of Congress and US Law, businesses above...

Tailpipe and evaporative emissions are controlled via the Clean Air Act so no they aren't going anywhere. Even if the Executive branch could gut itself to the point of non-viability for enforcement, the manufacturers are still liable to follow the law. There's no support in the Congress to roll...

That crowd might as well be raccoons attempting to decipher a SpaceX rocket. Whole lotta hearsay without evidence to back it up.

As usual politicians like to say they're doing something when in reality not doing anything at all. As of now they're still debating whether EPA waiving preemption for California is a "rule" or not. GAO says no, so it'll probably wind up on the appellate ladder. That doesn't even get into the...

Statute of limitations on CAA knowing violations is 5 years just FYI. Since transportation emissions are included in all revisions of the CAA the overturning of Chevron really doesn't apply here. Be careful what "advice" you put on the Internet because it will live forever, unlike the current...

There's several different layers of irony with a Mexican-built truck pacing the president. All Trail Bosses are built in Silao.

That’s a lot of words to say “no I can’t back up my claims.” Transportation emissions have long shown to have seriously negative health effects to people with long commutes and those living near busy highways. Seeing as we have hundreds of millions of vehicles on the road it’s important those...

Cite your data to back this up. Since I know you can’t, the real reason these emissions control systems are important is diesel exhaust has an outsized influence on local air quality and health between smog forming emissions and particulate matter. “Carbon footprint” isn’t the be all end all...

If you get bored there’s a PDF floating around the web that can be found by searching TULA and DFM together. The skip fire technology is pretty slick and way more went into it than the old AFM system. Overall it’s worth 1-1.5 mpg in the fleet average for full size trucks and SUVs. Times that...

On a smaller, lighter vehicle it can save quite a bit of fuel. On a crew cab 4x4 pickup not so much.

Since the widespread adoption of electronic fuel injection in the late 80s every single OEM has employed deceleration fuel cutoff as a means to protect the catalytic converter and save fuel in the process. So if you’ve driven a vehicle built since then you’ve experienced it. Vehicles built in...

You aren't losing any, because the engine isn't activating DFM at 0% throttle. It's Deceleration Fuel Cutoff as I previously said. Don't take it from me, take it from GM's own words.
