Bully Dog and SCT Settles With Feds

But would you say a non cerified gas engine tune on a stock engine is the same as a tune to delete/or deactivate emissions equipment?

Yes, and even worse depending on the engine. In the case of direct injected engines, studies like Tuv Nord's 2012 report showing many emitting up to 10 times more PM than diesel. Gas engines(even with a cat) also emit more CO2 than diesels by nature which is what harms the environment more than PM or NOx.

Diesels also use less barrels of oil due their efficiency and even less when deleted due to the 2-3 mpg improvement so the added emissions for making those extra barrels of oil should be in the equation of overall emissions as well. Also, you have to take the factor that since a deleted diesel doesn't use DEF, then you don't have to factor in all of the waste and emissions from making and transporting DEF along with the plastic containers it comes in.

The one thing that diesels do emit a lot of is NOx which is harmful to humans in large quantities, but harmless in low quantities where it has time to dissipate into the stratosphere where it is good ozone. If you don't live in a heavily populated area, then you aren't putting enough in the air to impact anyone.

You can't say a deleted diesel burns cleaner than a stock one or we wouldn't have put DPF's/SCR on them in the first place.

I never said that so I am not sure where you are getting that from.

When is the last time a modern gasoline engine had EGR?

Many modern gas engines have EGR's. In fact all of the HD truck gasers have one, and all non-GDI half ton engines half them as well.

A tuned gasoline engine with cats and all emissions equipment in tact is allot different than a stock tuned diesel with emissions equipment removed/deactivated.

Not always especially on cold starts. You see cats have to be at a certain temp before they can actually work. In order to get the cat to operating temp quicker, most modern gas engines are prgrammed to run rich and dump a lot of added fuel similar to the fuel being dumped on a diesel when you see black smoke. The only difference is that you cannot see it on a gas engine, but just a s a tree in the woods, just because you can't see it doesn't mean it doesn't happen.

ALso, cats are wear items that degrade over time. I can guarantee you that there are many 10+ year gas engines out there that are spewing way more environmentally harmful emissions(aside from NOx) than a modern deleted diesel.
